Synthesis

edit

Dissolving lutetium oxide in nitric acid:

 

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

 

Physical properties

edit

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

edit

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:

 

Applications

edit

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.
