## Synthesis

Dissolving lutetium oxide in nitric acid:

[math]\displaystyle{ \mathsf{ Lu_2O_3 + 6HNO_3 \ \xrightarrow{90^oC}\ 2Lu(NO_3)_3 + 3H_2O } }[/math]

To obtain anhydrous nitrate, the powdered metal is added to nitrogen dioxide dissolved in ethyl acetate:

[math]\displaystyle{ \mathsf{ Lu + 3N_2O_4 \ \xrightarrow{77^oC}\ Lu(NO_3)_3 + 3NO } }[/math]

## Physical properties

Lutetium(III) nitrate forms colorless hygroscopic crystals.

Soluble in water and ethanol.

Forms crystalline hydrates of the composition Lu(NO3)3•nH2O, where n = 3, 4, 5, 6.[3]

## Chemical properties

The hydrated lutetium nitrate thermally decomposes to form LuONO3 and decomposes to lutetium oxide upon further heating.[4]

The compound forms ammonium hexafluoroluthenate with ammonium fluoride:

[math]\displaystyle{ \mathsf{ Lu(NO_3)_3 + 6 NH_4F \ \xrightarrow{}\ (NH_4)_3[LuF_6]\downarrow + 3NH_4NO_3 } }[/math]

## Applications

Lutetium(III) nitrate is used to obtain metallic lutetium and also as a chemical reagent.

It is used as a component of materials for the production of laser crystals.
