Anhydrous salt is obtained by the action of nitrogen dioxide on dysprosium(III) oxide:[3]
The action of nitrogen dioxide on metallic dysprosium:
Dysprosium(III) nitrate forms yellowish crystals.[4]
The anhydrous nitrate forms a crystalline hydrate in wet air with the ideal composition of Dy(NO3)3·5H2O, which melts in its own crystallization water at 88.6 °C.[5][6]
All hydrates (anhydrous, pentahydrate, and hexahydrate) are soluble in water and ethanol, hygroscopic.
Hydrated dysprosium nitrate thermally decomposes to form DyONO3,[citation needed] and further heating produces dysprosium oxide.
Dysprosium(III) nitrate is used as a catalyst.
