Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

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]

Contents

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 ↑

Properties

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 ]

Applications

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