Synthesis

Dissolving metallic erbium in nitric acid:

:{{chem2 | Er + 6 HNO3 -> Er(NO3)3 + 3 NO2 + 3 H2O ↑ }}

Dissolving erbium oxide or hydroxide in nitric acid:

:{{chem2 | Er(OH)3 + 3 HNO3 -> Er(NO3)3 + 3 H2O ↑ }}

Reaction of nitrogen dioxide with metallic erbium:

:{{chem2 | Er + 3 N2O4 -> Er(NO3)3 + 3 NO ↑ }}

Physical properties

Erbium(III) nitrate forms pink hygroscopic crystals.

Forms crystalline hydrates of the composition {{chem2 | Er(NO3)3*5H2O }}.

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

Dissolves in water and EtOH.{{cite book |last1=Sr |first1=Richard J. Lewis |title=Hazardous Chemicals Desk Reference |date=13 June 2008 |publisher=John Wiley & Sons |isbn=978-0-470-18024-2 |page=591 |url=https://books.google.com/books?id=WZeBDwAAQBAJ&dq=Erbium(III)+nitrate&pg=PA591 |access-date=19 August 2021 |language=en}}

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.
