Physical and chemical properties

Antimony trioxide is a white cubic crystal; melting point 656°C, relative density 5.2; amphoteric, stronger than acid; easily soluble in acid; solubility in water is 0.002 g/100 ml water. Antimony trioxide turns yellow when heated to 300-400°C in air, and antimony (III) antimonate (SbIII(SbVO4)) is obtained, with a relative density of 5.82. When strongly heated, it releases oxygen to become antimony trioxide. Antimony trioxide and strong alkali are melted to obtain M2SbIII(SbIIIO4) type salt (M is a monovalent metal). Sb2O3 vapor molecules are dimers Sb4O6, which begin to dissociate into Sb2O3 above 800°C and almost completely dissociate at 1800°C.

Antimony pentoxide is a light yellow powder; it is insoluble in water and slightly soluble in alkali to form antimonate.

Uses of antimony trioxide

Because it is a heavy gas, Sb2O3 can extinguish flames. Mainly used in fire-retardant coatings. Antimony trioxide is a white pigment used in paint and other industries, and can be used to prepare various antimonides. As a flame retardant, it can be widely used in polyethylene, polypropylene, polystyrene, polyvinyl chloride, nylon, engineering plastics (ABS), rubber, paint, coating, synthetic resin, paper and other materials. As a defoamer, it is used to remove bubbles in melted glass and as a catalyst in polyester fibers. It is used as a covering agent and whitening agent in enamel and ceramic products. It is used as a passivating agent in heavy oil, residual oil, catalytic cracking, and catalytic reforming processes in petroleum.
