Antimony trioxide CasNo.: 1309-64-4 is commonly known as antimony white, in the form of white powder ,is an amphoteric oxide , insoluble in water, ethanol , dilute sulfuric acid and dilute nitric acid, but soluble in concertrated hydrochloric acid , sulfuric acid, strong alkali and tartaric acid solution , the Molecular formula is Sb2O3, the molecular weight is 291.5 , the density is 5.3g/cm3,  the melting point is 656 cet degree. And the boiling point is 1570 cet degree


Widely applied as anti-flaming agent in PVC, PP, PE, PS, ABS, PU and other plastic, with high anti-flaming efficiency, producing less effect on mechanic performance of basic materials( e.g. fire control uniforms, gloves, case of anti-flaming electronic equipment, anti-flaming carriage, anti-flaming wire and cable, etc. )

  1. Used as filling agent and flame retardant in rubber industry.
  2. Used as covering agent in porcelain enamel and ceramics.
  3. Used as non-magnetic ceramics used for making pressure sensitive ceramics and magnet head parts in electronic industry Antimony trioxide CasNo.: 1309-64-4
