Physical propertiesEdit

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]


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