About Antimony trioxide
Antimony trioxide is the inorganic compound with the formula Sb2O3.. Also known as Antimonous oxide, it is an amphoteric oxide, it dissolves in aqueous sodium hydroxide solution to give the meta-antimonite NaSbO2. When heated with carbon, the oxide is reduced to antimony metal.
The main application is as flame retardant synergist in combination with halogenated materials. Antimony(III) oxide is an opacifying agent for glasses, ceramics and enamels. Antimony(III) oxide is a useful catalyst in the production of polyethylene terephthalate (PET plastic) and the vulcanization of rubber.
