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]

Synthesis

Dissolving metallic erbium in nitric acid:

Er + 6 HNO3 → Er(NO3)3 + 3 NO2 + 3 H2O ↑

Dissolving erbium oxide or hydroxide in nitric acid:

Er(OH)3 + 3 HNO3 → Er(NO3)3 + 3 H2O ↑

Reaction of nitrogen dioxide with metallic erbium:

Er + 3 N2O4 → Er(NO3)3 + 3 NO ↑

Physical properties

Erbium(III) nitrate forms pink hygroscopic crystals.

Forms crystalline hydrates of the composition Er(NO3)3·5H2O.

Both erbium(III) nitrate and its crystalline hydrate decompose on heating.

Dissolves in water and EtOH.[6]

Chemical properties

The hydrated erbium nitrate thermally decomposed to form ErONO3 and then to erbium oxide.

Applications

It is used to obtain metallic erbium and is also used as a chemical reagent.
