The fishing tackle (strapped to the end of your fishhook) is made of an alloy called lead-antimony. It has five antimony-fluorine bonds. Workers may be harmed from exposure to antimony and its compounds. [46], Reported production of antimony in China has fallen and is unlikely to increase in the coming years, according to the Roskill report. There are four known antimony allotropes: stable metallic antimony; and 3 meta-stable forms (yellow, black and explosive). What is Antimony? Antimony compounds (especially the trioxide) are widely used as flame retardants in paints, plastics, rubber, and textiles. Antimony is considered to be a “strategic metal” and wartime applications include antimony oxide used as a flame retardant in plastics and textiles for vehicles and aircraft, antimony metal used in storage batteries and in ordnance to harden lead, and antimony tri-sulfide for primers in ordnance and rockets.. 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. Four allotropes of antimony are known: a stable metallic form and three metastable forms (explosive, black and yellow). 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. [21], An artifact, said to be part of a vase, made of antimony dating to about 3000 BC was found at Telloh, Chaldea (part of present-day Iraq), and a copper object plated with antimony dating between 2500 BC and 2200 BC has been found in Egypt. Babbit metals, used for machinery bearings, are alloys of lead, tin, copper and antimony. [citation needed]. The ancient words for antimony mostly have, as their chief meaning, kohl, the sulfide of antimony. Antimony trioxide dissolves in concentrated acid to form oxoantimonyl compounds such as SbOCl and (SbO)2SO4. 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. According to the BGS Risk List 2015, antimony is ranked second highest (after rare earth elements) on the relative supply risk index. It is Lewis acidic and readily accepts fluoride ions to form the complex anions SbF−4 and SbF2−5. (1) Sources and Potential Exposure Antimony is found at very low levels throughout the 3) However because of its limited supply globally, it is often mixed with other metal. What is Antimony Used for Today Modern uses of Antimony also take advantage of its hardening effect in alloys. [89] The IDLH (immediately dangerous to life and health) value for antimony is 50 mg/m3. Elemental antimony metal does not affect human and environmental health. The Latin name of Antimony is Stibium. Babbit metals, used for machinery bearings, are alloys of lead, tin, copper and antimony. Later Latin authors adapted the word to Latin as stibium. 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. [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. interests. Pliny also gives the names stimi [sic], larbaris, alabaster, and the "very common" platyophthalmos, "wide-eye" (from the effect of the cosmetic). 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. antimony ore used for what product congo south africa antimony ore company directory . It was subsequently replaced by praziquantel. Symbol: … Antimony Facts | Uses and Application What is Antimony? Antimony is a semi-metallic chemical element with an atomic number 51 and symbol Sb in the Periodic Table. The capability to strengthen already strong alloys is its largest and most widespread use. Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. [25] A description of a procedure for isolating antimony is later given in the 1540 book De la pirotechnia by Vannoccio Biringuccio,[26] predating the more famous 1556 book by Agricola, De re metallica.
