Documented Uses

• The greatest use of antimony compounds is in flame retardants for plastics, paints, textiles, and rubber. Antimony compounds used in flame retardants are antimony pentoxide, sodium antimonate ... and, most importantly, antimony trioxide. These compounds, when used alone, are poor flame retardants; however, when combined with halogen compounds, they produce mixtures that are effective. ... Glass articles coated with oxides and oxynitrides of antimony have been reported. The layers of antimony block uv radiation and
• Laboratory chemicals; Synthesis of substances.
• Antimony triiodide is prepared by reacting iodine with antimony or antimony sulfide in an organic solvent.
• Prepared by the interaction of antimony and iodine in boiling benzene or tetrachloroethane.
• Antimony can be trivalent or pentavalent in compounds. Both exist in antimony(IV) oxide, Sb2O4, and presumably in the deep violet haloantimonates (IV), such as Cs2(SbCl6). The pentavalent compounds, as well as most of the trivalent ones, are hydrolyzed by water to form antimony salts, e.g., SbOCl, and hydrated oxides. The only halides of antimony that have any industrial significance are the chlorides and fluorides. /Antimony compounds/
