Antimony trioxide(antimonous 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. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions only with hydrolysis.
Item Name: antimonous oxideScope of application: Enamel, paint, paint, ceramics, metallurgy, chemical industry, etc.
Technical standard: GB/T 4062-1998

Antimony trioxide is an amphoteric oxide, dissolving in alkaline solution to give antimonites and in acid solution to given a range of polyantimonous acids. It can be readily oxidized to antimony pentoxide and related antimony(V) compounds, but it is also easily reduced to antimony, sometimes with production of stibine.
