Curium(III) nitrate is an inorganic compound, a salt of curium and nitric acid with the chemical formula Cm(NO3)3.[1][2][3]
Synthesis
[edit]Reaction of curium and nitric acid:[4]
- Cm + 4 HNO3 → Cm(NO3)3 + NO + 2 H2O
Physical properties
[edit]Curium(III) nitrate is a solid that exists as a hydrate or anhydrate, depending on the synthesis. The hydrates melt at 90 and 180 °C in crystallization water. The anhydrate decomposes to curium(IV) oxide at temperatures above 400 °C.[5]
Applications
[edit]Curium(III) nitrate can be used to make curium(IV) oxide.
