Sb2O5
Sb2O5, or antimony pentoxide, is an inorganic compound consisting of antimony in the +5 oxidation state and oxide. It is typically described as a white to pale yellow powder and is used mainly as a laboratory reagent and synthetic intermediate. In its anhydrous form it is relatively stable under ambient conditions but is poorly soluble in water.
The solid forms a polymeric oxide framework built from SbO6 coordination, and the precise arrangement can vary
Sb2O5 can be prepared by oxidizing Sb2O3 at elevated temperatures in air. It can also arise from
Sb2O5 is mainly used as a starting material for the synthesis of other antimony(V) compounds and as
Antimony compounds can be hazardous if mishandled. Sb2O5 should be handled with appropriate PPE to avoid inhalation
