Forms crystalline hydrates of the composition .
Both erbium(III) nitrate and its crystalline hydrate decompose on heating.
Dissolves in water and EtOH.[6]
Chemical properties
[edit]The hydrated erbium nitrate thermally decomposed to form ErONO3 and then to erbium oxide.
Applications
[edit]It is used to obtain metallic erbium and is also used as a chemical reagent.
