Chemical compound

Curium(III) nitrate is aninorganic compound, a salt ofcurium andnitric 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 incrystallization 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.
