Antimony trioxide
We are manufacturing Antimony Trioxide in various forms.
ie; AR, LR and Technical Grade. These all grades are available in 5 kg pack to 50 kg packing in HDPE Drums or Bags.
Antimony trioxide 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
Antimony trioxide is an amphoteric oxide, it dissolves in aqueous sodium hydroxide solution to give the meta-antimonite NaSbO2, which can be isolated as the Trihydrate. Antimony trioxide also dissolves in concentrated acids to give the corresponding salts, which hydrolyzes upon dilution with water. With nitric acid, the trioxide is oxidized to antimony(V) oxide.
CAS No: (1309-64-4)
