Following the war, the automobile industry in the US stimulated new demand for antimony products through the use of lead-acid batteries where it is alloyed with lead to hardening the grid plate material. [73] Antimony compounds are used as antiprotozoan drugs. Antimony has been used in a variety of applications for 2,000 years, and today is most commonly found alloyed with other elements. The level of exposure depends upon the dose, duration, and work being done. Workers may be harmed from exposure to antimony and its compounds. These include primarily . Powered by, Trustway Metal - Designed by, Ulysses W. Trustway - Privacy. Historically, the powder derived from crushed antimony (kohl) has been applied to the eyes with a metal rod and with one's spittle, thought by the ancients to aid in curing eye infections. Our pocket calculators, computer games, and portable stereos have small amounts o… Antimony trioxide is the most important of the antimony compounds and is primarily used in flame-retardant formulations. Antimony oxide is a brilliant yellow color, accounting for much of the pigment use. [14] In the gas phase, the molecule of the compound is Sb4O6, but it polymerizes upon condensing. They are also added to polyester resins in fiberglass composites for such items as light aircraft engine covers. The yellow allotrope of antimony is the most unstable. Biology and medicine have few uses for antimony. It was used in glaze and pigment in ancient Babylon, and in the Middle Ages it was used to harden lead to make move typeface after the invention of the printing press. Very pure antimony is used to make certain types of semiconductor devices, such as diodes and infrared detectors. Nowadays, antimony is mostly [23], The first discovery of naturally occurring pure antimony in the Earth's crust was described by the Swedish scientist and local mine district engineer Anton von Swab in 1783; the type-sample was collected from the Sala Silver Mine in the Bergslagen mining district of Sala, Västmanland, Sweden.[30][31]. In the antimony ore mining process, Mining Co. can supply you all kinds fo antimon JC La Trituración de Mandíbula Trituradora de Mandíbula HJ Trituradora ), Oxford: Butterworth-Heinemann. When alloyed with other metals, antimony is known to increase the hardness of a product. Greenwood, N. N.; & Earnshaw, A. According to the National Bureau of Statistics in China, by September 2015 50% of antimony production capacity in the Hunan province (the province with biggest antimony reserves in China) had not been used. Symbol: … Antimony oxide is used as a catalyst in the esterification of high-molecular-weight polyethylene terephthalate resins and fibers. It is alloyed with lead or other metals to improve their hardness and strength. Antimony is used for a wide array of industrial applications, including many paints, batteries, and rubber. Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. Elemental antimony metal does not affect human and environmental health. In 2015, no antimony was mined in the U.S. The drinking water guidelines are: The TDI proposed by WHO is 6 µg antimony per kilogram of body weight. Antimony alloys are also used in batteries, low friction metals, type metal and cable sheathing, among other products. The major use of antimony is in lead alloys – mainly for use in batteries – adding hardness and smoothness of finish. Antimony can also cause problems with the lungs, heart, and stomach. Antimony is resistant to acid attacks. The higher the proportion of antimony in the alloy, the harder and more brittle it will be. Antimony forms a highly useful alloy with lead, increasing its hardness and mechanical strength. Potassium antimonyl tartrate, or tartar emetic, was once used as an anti-schistosomal drug from 1919 on. The fishing tackle (strapped to the end of your fishhook) is made of an alloy called lead-antimony. Highly purified antimony is used in semiconductor technology to prepare the intermetallic compounds indium, aluminum, and gallium antimonide for diodes and infrared detectors. Pliny also gives the names stimi [sic], larbaris, alabaster, and the "very common" platyophthalmos, "wide-eye" (from the effect of the cosmetic). The trihalides SbF3, SbCl3, SbBr3, and SbI3 are all molecular compounds having trigonal pyramidal molecular geometry. Antimony has consistently been ranked high in European and US risk lists concerning criticality of the element indicating the relative risk to the supply of chemical elements or element groups required to maintain the current economy and lifestyle. Chemistry of the Elements (2nd Edn. (adsbygoogle = window.adsbygoogle || []).push({}); I have always believed in helping others by sharing what I have learned. In fact, Guizhou, China used antimony to make coins in 1931, but discontinued minting them due to their poor durability. [67] The third application is pigments. These two factors increase supply risk for both Europe and US. Antimony oxides (primarily antimony trioxide) are used as fire retardants for plastics, textiles, rubber, adhesives, pigments, and paper. a chemical element, atomic number 51, atomic weight 121.75. Drugs.com Mobile Apps The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. Above this temperature and in ambient light, this metastable allotrope transforms into the more stable black allotrope. (See Appendix 6.) A lead-antimony alloy is used in batteries. [32][better source needed] However, the low toxicity of Antimony (see below) makes this unlikely. Ithmid (antimony) Kohl is special because unlike other types of Kohl it … Antimony(III) sulfide, Sb2S3, was recognized in predynastic Egypt as an eye cosmetic (kohl) as early as about 3100 BC, when the cosmetic palette was invented. However, the USGS expects more resources will be found. As China is revising and increasing environmental control standards, antimony production is becoming increasingly restricted. It is often alloyed with lead and with tin, and is widely employed for lead-acid battery plates, bullets and cable sheathing. Littré suggests the first form, which is the earliest, derives from stimmida, an accusative for stimmi. Antimony, the 51st element on the periodic table (symbol: Sb), is a shiny, silver-gray metal that has been used by mankind for millennia. Babbit metals, used for machinery bearings, are alloys of lead, tin, copper and antimony. Finding scrap made of pure antimony will definitely brighten the day because it is worth more than copper. [13] The +5 oxidation state is more stable. [23], The intentional isolation of antimony is described by Jabir ibn Hayyan before 815 AD. Antimony is a shiny gray metalloid which exists in nature as sulfide mineral stibnite. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. For other uses, see, Antimonides, hydrides, and organoantimony compounds, Supply risk and critical mineral rankings, Already in 1710 Wilhelm Gottlob Freiherr von. Scrap yards may start requesting antimony scrap specifically or items containing antimony. [85] The practice is still seen in Yemen and in other muslim countries. Definition and meaning:ANTIMONY an'-ti-mo-ni. Antimony definition, a brittle, lustrous, white metallic element occurring in nature free or combined, used chiefly in alloys and in compounds in medicine. [7] Antimony is resistant to attack by acids. Although current known global reserves are expected to be depleted in approximately 13 years, and a shortage would dramatically affect the Western economy and lifestyle (according to a UK government report), scientists expect that more deposits will be discovered. But to achieve such an expression can be through the make-up of antimony - colorant that Arab beauties used for eyeliner, age toning, and even the treatment of the eye. Antimony can be isolated from the crude antimony sulfide by reduction with scrap iron:[50], The sulfide is converted to an oxide; the product is then roasted, sometimes for the purpose of vaporizing the volatile antimony(III) oxide, which is recovered. [74] Antimony and its compounds are used in several veterinary preparations, such as anthiomaline and lithium antimony thiomalate, as a skin conditioner in ruminants. [86] Antimony compounds are used as catalysts for polyethylene terephthalate (PET) production. Antimony is alloyed with lead to increase lead's durability. Antimony is a rare element but can sometimes be found naturally. Babbit metals, used for machinery bearings, are alloys of lead, tin, copper and antimony. You can also find tin antimony solder. Especially due to a new environmental protection law having gone into effect in January 2015[45] and revised "Emission Standards of Pollutants for Stanum, Antimony, and Mercury" having gone into effect, hurdles for economic production are higher. Sb Element (Antimony) - Antimony is chemical element number 51, with atomic weight 122, chemical symbol Sb, and is a member of group 15 of the periodic table. It also is used in semiconductors, diodes, infrared detectors, batteries and bullets. These metals are hard but slippery and so ideal for use as bearings. These include ovenproof or microwavable plastic trays, as As you have read, scrap in the future will be much more than metal goods. Today antimony is produced in a handful of countries, including China, which holds 75 percent of the world’s reserves, and accounts for almost 90 percent of world production, which totaled 135,000 metric tonnes in 2010. What is Antimony used for? [75] Antimony has a nourishing or conditioning effect on keratinized tissues in animals. Synthetic fibers are the most popular fibers in the world with 65% of world production of fibers being synthetic and 35% natural fibers. Available for Android and iOS devices. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. 166) in which layers consist of fused, ruffled, six-membered rings. When slowly cooled, molten antimony crystallizes in a trigonal cell, isomorphic with the gray allotrope of arsenic. The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron. Xikuangshan Mine in Hunan province has the largest deposits in China with an estimated deposit of 2.1 million metric tons. Elschenbroich, C. "Organometallics" (2006) Wiley-VCH: Weinheim. An emerging application is the use of antimony in microelectronics. [90] Effects may be similar to arsenic poisoning. congo brazaville begins exporting iron ore – africa congo brazaville begins exporting iron ore. pointe noire. What is Antimony? [23], With the advent of challenges to phlogiston theory, it was recognized that antimony is an element forming sulfides, oxides, and other compounds, as do other metals. Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb2O3.[6]:758. As a result of its wide use in various non-recyclable materials and its toxic properties, antimony is often spoken of in the context of environmental problems or … 1 Fully 70% of that synthetic fiber production is polyester. It has five antimony-fluorine bonds. In use, it is swallowed and allowed to pass through the body, after which it is customarily recovered for reuse, giving rise to the name everlasting pill.The antimonial cup yielded the same effect. Antimony isn't used alone because it breaks easily, but when mixed into alloys, it is used in lead storage batteries, solder, sheet and pipe metal, bearings, castings, and pewter. USES OF ANTIMONY (U.S.G.S.) It found that a small subset of minerals including antimony has fallen into the category of potentially critical minerals consistently. [37][38], The standard chemical symbol for antimony (Sb) is credited to Jöns Jakob Berzelius, who derived the abbreviation from stibium.[39]. It has only been generated by oxidation of stibine (SbH3) at −90 °C. "[22] This weakens the evidence for a lost art "of rendering antimony malleable. The periodic table symbol Sb comes from the Latin word “stibium,” itself a derivation of “stibbi,” which was used by Pliny in the 1st Century AD. These metals are hard but slippery and so ideal fo… The ore antimony trisulfide (Sb2S3) was used in paste form, as a cosmetic Antimony(V) is not quantitatively reduced to antimony(III) in the cell, and both species exist simultaneously. Relatively rare, it is sometimes found as a base metal, but more often occurs bound to other elements in one of up to 100 mineral compounds. Learn applications, properties, health effects & uses of The book Currus Triumphalis Antimonii (The Triumphal Chariot of Antimony), describing the preparation of metallic antimony, was published in Germany in 1604. Alloyed with lead, it greatly improves the strength and hardness of lead. [50], Antimony is increasingly being used in semiconductors as a dopant in n-type silicon wafers[68] for diodes, infrared detectors, and Hall-effect devices. [citation needed] Stibine decomposes spontaneously at room temperature. Antimony is used to make useful alloys to increase mechanical strength and hardness. Because stibine has a positive heat of formation, it is thermodynamically unstable and thus antimony does not react with hydrogen directly.[13]. Alloys of lead and tin with antimony have improved properties for solders, bullets, and plain bearings. For most applications involving lead, varying amounts of antimony are used as alloying metal. [6]:757 Antimony pentasulfide is non-stoichiometric and features antimony in the +3 oxidation state and S–S bonds. It has the same crystal structure as red phosphorus and black arsenic; it oxidizes in air and may ignite spontaneously. [35] Several authorities believe antimonium is a scribal corruption of some Arabic form; Meyerhof derives it from ithmid;[36] other possibilities include athimar, the Arabic name of the metalloid, and a hypothetical as-stimmi, derived from or parallel to the Greek. It is used to make flame-proofing materials and in some paints, glass, and batteries. Harold Jantz was perhaps the only modern scholar to deny Thölde's authorship, but he too agrees the work dates from after 1550: see his, Meyerhof as quoted in Sarton, asserts that, In his long article on chemical reactions and nomenclature – Jöns Jacob Berzelius, "Essay on the cause of chemical proportions, and on some circumstances relating to them: together with a short and easy method of expressing them,", Grund, Sabina C.; Hanusch, Kunibert; Breunig, Hans J.; Wolf, Hans Uwe (2006) "Antimony and Antimony Compounds" in, risk lists concerning criticality of the element, American Conference of Governmental Industrial Hygienists, Occupational Safety and Health Administration, National Institute for Occupational Safety and Health, United States Environmental Protection Agency, "Atomic weights of the elements 2013 (IUPAC Technical Report)", "Studies of N-heterocyclic Carbene (NHC) Complexes of the Main Group Elements", "XL. For instance, it is used in alloying of lead that is used in acid batteries to improve charging features. However, it was agreed at the European Union level that the skin rashes observed are not substance-specific, but most probably due to a physical blocking of sweat ducts (ECHA/PR/09/09, Helsinki, 6 July 2009). Inhalation absorption of antimony trioxide and other poorly soluble Sb(III) substances (such as antimony dust) is estimated at 6.8% (OECD, 2008), whereas a value <1% is derived for Sb(V) substances. There are four known antimony allotropes: stable metallic antimony; and 3 meta-stable forms (yellow, black and explosive). [6] Antimony pentoxide (Sb4O10) can be formed only by oxidation with concentrated nitric acid. Molten SbF3 is a weak electrical conductor. Antimony-124 is used together with beryllium in neutron sources; the gamma rays emitted by antimony-124 initiate the photodisintegration of beryllium. In the future, a second assessment will be made of the found subset of minerals to identify which should be defined of significant risk and critical to U.S. It is used in medicines for pets. Antimony Facts | Uses and Application What is Antimony? The most important use of antimony in the United States is in chemicals used to impregn… Antimony alloys are also used in batteries, low friction metals, type metal and cable sheathing, among other products. native metal) and that "the antimony objects from Transcaucasia are all small personal ornaments. One popular theory for the origin of the name Antimony is that it comes from the ancient Greek “antimonos,” which can be translated as “not alone,” reflecting the fact that the element is almost always found in compounds. Several other antimony compounds are used as paint pigments; tartar emetic (an organic salt of antimony) is used in the textile industry to aid in binding certain dyes to fabrics and in medicine as an expectorant and a nauseant. An alloy of lead and antimony is used in batteries, low friction metals, small arms and tracer bullets, cable sheathing as well as other products. However, it’s mostly in the form of its sulfide stibnite. However because of its limited supply globally, it is often mixed with other metal. [55], Much analysis has been conducted in the U.S. toward defining which metals should be called strategic or critical to the nation's security. It is unclear if antimony can enter the body through the skin. The ancient Egyptians used antimony, in the form of stibnite, for black eye make-up. Antimony dust may also be explosive when dispersed in the air; when in a bulk solid it is not combustible. Dermal absorption for metals is estimated to be at most 1% (HERAG, 2007). Antimony trioxide dissolves in concentrated acid to form oxoantimonyl compounds such as SbOCl and (SbO)2SO4. When scratched with a sharp implement, an exothermic reaction occurs and white fumes are given off as metallic antimony forms; when rubbed with a pestle in a mortar, a strong detonation occurs. Antimony is dissolved in hot concentrated sulphuric acid, H 2 SO 4, or nitric acid, HNO 3, forming Sb(III) solutions. These include ovenproof or microwavable plastic trays, as well as some plastic water bottles. [11], The abundance of antimony in the Earth's crust is estimated to be 0.2 to 0.5 parts per million, comparable to thallium at 0.5 parts per million and silver at 0.07 ppm. Stibnite is used for metal antifriction alloys, metal type, shot, batteries, and in the manufacture of fireworks. It is generally found in two forms namely metallic form and non-metallic form. [86], Certain compounds of antimony appear to be toxic, particularly antimony trioxide and antimony potassium tartrate. Antimony is used as a hardening alloy for lead, especially in storage batteries and cable sheaths, and also used in bearing metal, type metal, solder, collapsible tubes and foil, sheet and pipes, and semiconductor technology. Antimony is a silvery, lustrous gray metalloid with a Mohs scale hardness of 3, which is too soft to make hard objects; coins of antimony were issued in China's Guizhou province in 1931 but the durability was poor and the minting was soon discontinued. (adsbygoogle = window.adsbygoogle || []).push({}); It was purported to be written by a Benedictine monk, writing under the name Basilius Valentinus in the 15th century; if it were authentic, which it is not, it would predate Biringuccio. Some examples of workers at risk [50], Antimony is mainly used as the trioxide for flame-proofing compounds, always in combination with halogenated flame retardants except in halogen-containing polymers. Elemental antimony is a brittle, silver-white shiny metalloid. Antimony is used as a catalyst in the production of polyester. Symbol: … [54] This indicates that it has currently the second highest supply risk for chemical elements or element groups which are of economic value to the British economy and lifestyle. Some 60 percent of all antimony produced today is used in the clothing and fabric industries in flame retardants, most often in its trioxide form, since the material inhibits combustion by reacting with oxygen and hydrogen atoms. When used as an alloying element, antimony greatly increases the hardness and mechanical strength of lead. More recently the semiconductor and microelectronics industry has begun using its compounds in the manufacture of silicon wafers, diodes and other components. Antimony is used in antifriction alloys (such as Babbitt metal),[62] in bullets and lead shot, electrical cable sheathing, type metal (for example, for linotype printing machines[63]), solder (some "lead-free" solders contain 5% Sb),[64] in pewter,[65] and in hardening alloys with low tin content in the manufacturing of organ pipes. The most common of these is the sulfide stibnite (Sb₂S₃), which was used by the ancient Egyptians for eye mascara, and today yields pure Antimony through a process of oxidation and then reduction using iron or carbon. The largest applications for metallic antimony are an alloy with lead and tin and the lead antimony plates in lead–acid batteries. The most stable of these is 120m1Sb with a half-life of 5.76 days. It could be reused by others after ingestion and elimination.[77]. [89] The IDLH (immediately dangerous to life and health) value for antimony is 50 mg/m3. It is mainly sourced in China in its sulfide mineral stibnite form. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic. The Egyptians called antimony mśdmt;[40][41] in hieroglyphs, the vowels are uncertain, but the Coptic form of the word is ⲥⲧⲏⲙ (stēm). The Greek word, στίμμι stimmi, is probably a loan word from Arabic or from Egyptian stm[32][better source needed], and is used by Attic tragic poets of the 5th century BC. [8][9][10], Elemental antimony adopts a layered structure (space group R3m No. [44], Chinese production of antimony is expected to decline in the future as mines and smelters are closed down by the government as part of pollution control. 'Shrapnel' (the ammunition) was widely used during World War I, resulting in the global production of antimony more than doubled to a peak of 82,000 tons in 1916. The 8-hour time-weighted average (TWA) is set at 0.5 mg/m3 by the American Conference of Governmental Industrial Hygienists and by the Occupational Safety and Health Administration (OSHA) as a legal permissible exposure limit (PEL) in the workplace. [69] Indium antimonide is used as a material for mid-infrared detectors.[70][71][72]. The resin will burn in the presence of an externally generated flame, but will extinguish when the external flame is removed.[51][60]. Besides having low therapeutic indices, the drugs have minimal penetration of the bone marrow, where some of the Leishmania amastigotes reside, and curing the disease – especially the visceral form – is very difficult. Antimony concentrations in fruit juice concentrates were somewhat higher (up to 44.7 µg/L of antimony), but juices do not fall under the drinking water regulations. [90] The presence of low levels of antimony in saliva may also be associated with dental decay.
