Reaction of nitrogen dioxide with metallic erbium:
Erbium(III) nitrate forms pink hygroscopic crystals.
Forms crystalline hydrates of the composition .
Both erbium(III) nitrate and its crystalline hydrate decompose on heating.
The hydrated erbium nitrate thermally decomposed to form ErONO3 and then to erbium oxide.
It is used to obtain metallic erbium and is also used as a chemical reagent.
