ANTIMONY (IV) OXIDE Usage And Synthesis

Chemical Properties

Antimony (IV) oxide are minute, lustrous crystals, yellow when heated. Infusible. Decomposes to Sb2O3 and O2 at very high temperatures. Virtually insoluble in water, dilute acids and alkalis. Soluble in hot concentrated HCl and concentrated H2SO4. Cubic or rhombic crystals.

Preparation

Antimony (V) oxide is ignited to red heat for about two weeks in a Pt crucible at 800-900°C.
Other method: boiling Sb2O3 with nitric acid, evaporating until fuming, and igniting as above.
