Infobox references

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 HNO
3
→ Cm(NO
3
)
3
+ NO + 2 H

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.
