Infobox references

Lutetium(III) nitrate is an inorganic compound, a salt of lutetium and nitric acid with the chemical formula Lu(NO3)3. The compound forms colorless crystals, dissolves in water, and also forms crystalline hydrates.[1] The compound is poisonous.[2]

Synthesis

Dissolving lutetium oxide in nitric acid:

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

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:

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.
