Erbium(III) nitrate is an inorganic compound, a salt of erbium and nitric acid with the chemical formula Er(NO3)3. [2] [3] [4] The compound forms pink crystals, readily soluble in water. A pentahydrate and hexahydrate also exist. [5] [6]

Reaction of nitrogen dioxide with metallic erbium:
Both erbium(III) nitrate and its crystalline hydrate decompose on heating. The hydrated erbium nitrate thermally decomposes to form ErONO3 and then erbium oxide.[ citation needed ]
It is used to obtain metallic erbium and is also used as a chemical reagent.
