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]
- [math]\displaystyle{ \mathsf{2Dy_2O_3 + 9N_2O_4 \ \xrightarrow{150^oC}\ 4Dy(NO_3)_3 + 6NO } }[/math]
The action of nitrogen dioxide on metallic dysprosium:
- [math]\displaystyle{ \mathsf{Dy + 3N_2O_4 \ \xrightarrow{200^oC}\ Dy(NO_3)_3 + 3NO } }[/math]
Physical properties
Dysprosium(III) nitrate forms yellowish crystals.[4]
Forms a crystalline hydrate of the composition [math]\ce{ Dy(NO3)3*5H2O }[/math], which melts in its own crystallization water at 88.6 °C.[5][6]
Soluble in water and ethanol, hygroscopic.
Chemical properties
Hydrated dysprosium nitrate thermally decomposes to form [math]\ce{ DyONO3 }[/math], and further heating produces dysprosium oxide.
Application
Dysprosium(III) nitrate is used as a catalyst.
