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.^[2]

Synthesis

Anhydrous salt is obtained by the action of nitrogen dioxide on dysprosium(III) oxide:^[3]

{\mathsf {2Dy_{2}O_{3}+9N_{2}O_{4}\ {\xrightarrow {150^{o}C}}\ 4Dy(NO_{3})_{3}+6NO}}

The action of nitrogen dioxide on metallic dysprosium:

{\mathsf {Dy+3N_{2}O_{4}\ {\xrightarrow {200^{o}C}}\ Dy(NO_{3})_{3}+3NO}}

Physical properties

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.

Chemical properties

Hydrated dysprosium nitrate thermally decomposes to form DyONO₃,^{[citation needed]} and further heating produces dysprosium oxide.

Application

Dysprosium(III) nitrate is used as a catalyst.
