Antimony Pentoxide

We are manufacturing Antimony Pentoxide 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 Pentoxide (Sb2O5) is a chemical compound of antimony and oxygen. It always occurs in hydrated form, Sb2O5•nH2O. It contains antimony in the +5 oxidation state.

The hydrated oxide is insoluble in nitric acid, but dissolves in concentrated potassium hydroxide solution to give potassium hexahydroxoantimonate (V), KSb (OH)6.
