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

Reaction of curium and nitric acid: ^[4]

Cm + 4 HNO₃ → Cm(NO₃)₃ + NO + 2 H₂O

Physical properties

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

Curium(III) nitrate can be used to make curium(IV) oxide.
