Antimony Trioxide
Antimony trioxide is a pure white ultra-fine powder in cubic crystal system. It is the most stable compound of antimony, with the molecular weight 291.5 and melting point 656℃, cubic crystal type (a stable type) has the density of 5.3g/cm3. Antimony trioxide is also named antimony white, and belongs to amphoteric oxide. It is insoluble in water, ethanol, dilute sulfuric acid, dilute nitric acid, but soluble in concentrated hydrochloric acid, sulfuric acid, alkali, and tartaric acid.

Properties:
Antimony trioxide is a pure white ultra-fine powder in cubic crystal system. It is the most stable compound of antimony, with the molecular weight 291.5 and melting point 656℃, cubic crystal type (a stable type) has the density of 5.3g/cm3. Antimony trioxide is also named antimony white, and belongs to amphoteric oxide. It is insoluble in water, ethanol, dilute sulfuric acid, dilute nitric acid, but soluble in concentrated hydrochloric acid, sulfuric acid, alkali, and tartaric acid.
Purposes:
(1) Antimony trioxide is applied to plastic products such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, ABS resin, polyester, polyurethane foamed plastic, epoxy resin and phenolic resin, as well as synthetic fiber like polypropylene and polyester as flame retardant synergist in a large amount. Adding halogen flame retardant and antimony trioxide synergist in a certain ratio in high polymer materials may obviously improve OI of material burning. With a remarkable strong flame retardant effect and high cost performance, it is the most important flame retardant synergist.
(2) It is used as rubber filler, passivator of petrochemical industry, clarifier of glass manufacturing, colorant of ceramics and enamel industry, and used in manufacturing of photoelectric elements, solid lubricating materials, anti-fouling paint of vessels, medicine, etc.
