Dysprosium(III) nitrate is an inorganic compound, a salt of dysprosium and nitric acid with the chemical formula Dy(NO3)3. The compound forms yellowish crystals, dissolves in water, forms a crystalline hydrate.
Synthesis Anhydrous salt is obtained by the action of nitrogen dioxide on dysprosium(III) oxide:
The action of nitrogen dioxide on metallic dysprosium:
Physical properties Dysprosium(III) nitrate forms yellowish crystals.
The anhydrous nitrate forms a crystalline hydrate in wet air with the ideal composition of , which melts in its own crystallization water at 88.6 °C.
All hydrates (anhydrous, pentahydrate, and hexahydrate) are soluble in water and ethanol, hygroscopic.
Chemical properties Hydrated dysprosium nitrate thermally decomposes to form , and further heating produces dysprosium oxide.
Application Dysprosium(III) nitrate is used as a catalyst.
