Berkelium(IV) oxide, also known as berkelium dioxide, is a chemical compound with the formula BkO2. This compound slowly decays to californium(IV) oxide.[2] It can be converted to berkelium(III) oxide by hydrogen reduction at 600 °C.[3]
- 2BkO2 + H2 → Bk2O3 + H2O
Production
[edit]Berkelium(IV) oxide is produced by burning berkelium metal in air at 1200 °C. It can also be produced by reacting berkelium(III) oxide with oxygen at 600 °C.[3]
