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:

$\mathsf{2}\mathsf{D}{\mathsf{y}}_{\mathsf{2}}{\mathsf{O}}_{\mathsf{3}}\mathsf{+}\mathsf{9}{\mathsf{N}}_{\mathsf{2}}{\mathsf{O}}_{\mathsf{4}}\stackrel{150^{o}C}{\to }\mathsf{4}\mathsf{D}\mathsf{y}\mathsf{(}\mathsf{N}{\mathsf{O}}_{\mathsf{3}}{\mathsf{)}}_{\mathsf{3}}\mathsf{+}\mathsf{6}\mathsf{N}\mathsf{O}$

The action of nitrogen dioxide on metallic dysprosium:

$\mathsf{D}\mathsf{y}\mathsf{+}\mathsf{3}{\mathsf{N}}_{\mathsf{2}}{\mathsf{O}}_{\mathsf{4}}\stackrel{200^{o}C}{\to }\mathsf{D}\mathsf{y}\mathsf{(}\mathsf{N}{\mathsf{O}}_{\mathsf{3}}{\mathsf{)}}_{\mathsf{3}}\mathsf{+}\mathsf{3}\mathsf{N}\mathsf{O}$

Physical properties

Dysprosium(III) nitrate forms yellowish crystals.

Forms a crystalline hydrate of the composition $\mathrm{D}\mathrm{y}(\mathrm{N}\mathrm{O}{\phantom{A}}_3){\phantom{A}}_3\cdot 5\mathrm{H}{\phantom{A}}_2\mathrm{O}$, which melts in its own crystallization water at 88.6 °C.

Soluble in water and ethanol, hygroscopic.

Chemical properties

Hydrated dysprosium nitrate thermally decomposes to form $\mathrm{D}\mathrm{y}\mathrm{O}\mathrm{N}\mathrm{O}{\phantom{A}}_3$, and further heating produces dysprosium oxide.

Application

Dysprosium(III) nitrate is used as a catalyst.
