Antimony (CAS NO.7440-36-0) can be used in the manufacture Ⅲ ~ V family compound semiconductor, high purity alloys, antimony sulfide and used for cooling components and silicon, germanium crystals doped with agents.
Additionally,it is used as analytical reagent, but also for the preparation of alloys and salt ,but also for high-purity reagents and raw materials for the semiconductor
Industrial production of Antimony (CAS NO.7440-36-0) has distillation and zone melting method.
Distillation of antimony block by adding the reactor, which leads to chlorine chlorination reaction of antimony trichloride. Crude antimony trichloride will join the distiller, by adding a small amount of scrap metal antimony by vacuum distillation to remove its impurities antimony pentachloride, and then distilled under atmospheric pressure. To take 221 ~ 225 ℃ of the fractions by cooling crystallization obtained antimony trichloride, after reduction, the obtained purity metal antimony ≥ 99.999%. And then this metal antimony as raw material, purified by double distillation, the purity of obtained high-purity antimony ≥ 99.9999%.

HazardClass: 6.1
PackingGroup: III
An experimental poison by intraperitoneal route. Questionable carcinogen with experimental carcinogenic data. Moderate fire and explosion hazard in the forms of dust and vapor when exposed to heat or flame. See also POWDERED METALS. When heated or on contact with acid it emits toxic fumes of SbH3. Electrolysis of acid sulfides and stirred Sb halide yields explosive Sb. It can react violently with NH4NO3, halogens, BrN3, BrF3, HClO3, ClO, ClF3, HNO3, KNO3, KMnO4, K2O2, NaNO3, oxidants.
