Erbium(III) nitrate is an inorganic compound, a salt of erbium and nitric acid with the chemical formula Er(NO3)3. [1] [2] [3] The compound forms pink crystals, readily soluble in water, also forms crystalline hydrates. [4] [5]

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.
Dissolves in water and EtOH. [6]
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.
