Antimony trioxide is a white crystalline powder.


Antimony trioxide is not soluble in water and in nitric acid, not very soluble in diluted H2S04 and HCI but more soluble in these acid concentrates.


Antimony trioxide, is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite and is mainly produced via the smelting of stibnite ore, which is oxidised to crude Sb2O3 using furnaces operating at approximately 850 to 1,000 °C. Antimonious oxide is widely used as a flame retardant for rubber and plastic materials. In its pure state it is used in pharmaceutical products. In the chemical industry antimony trioxide is used as an intermediate for the preparation of metallic antimony; in the glass industry it is used to de-colourise glass, in the ceramic industry and in galvanic technology.


The toxicity of antimony trioxide is topical because it is a likely byproduct of the combustion of some materials "fireproofed" with antimony compounds. The oxides of arsenic, antimony, and bismuth are comparable in their toxicity, but their volatilities differ widely. Antimony trioxide has suspected carcinogenic potential for humans.
