Antimony(III) oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite.[2] Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions with hydrolysis.

White powder, insoluble in water, soluble in acid and sodium hydroxide solution. For the white pigments, paints and plastics, from pigments and flame retardant effect. The main purpose 1. For a variety of resins, synthetic rubber, canvas, paper, paint and other flame retardants, petrochemicals, synthetic catalysts. For the manufacture of mordant, white agent, antimony salt is synthesized. Enamel industry as additives to increase the opacity of enamel and surface gloss. Glass industry as a bleaching agent instead of arsenious acid. Pharmaceutical, metallurgical, military and other. 2. antimony trioxide flame retardant additive belonging, often with other flame retardants, smoke suppressants and use, between the component may produce a synergistic effect. Antimony trioxide in the early stages of combustion, first molten material isolated from the air surface protective film is formed by an internal endothermic reaction, reducing the combustion temperature. Antimony trioxide is gasified at a high temperature, dilute the concentration of oxygen in the air, and thus play a flame retardant.
