Holmium (III) nitrate is an inorganic compound, a salt of holmium and nitric acid with the chemical formula Ho(NO3)3.[1] The compound forms yellowish crystals, dissolves in water, also forms crystalline hydrates.[2]
Synthesis
[edit]Anhydrous salt is obtained by the action of nitrogen dioxide on holmium(III) oxide:
Effect of nitrogen dioxide on metallic holmium:
Reaction of holmium hydroxide and nitric acid:
Physical properties
[edit]Holmium(III) nitrate forms yellowish crystals.
Forms a crystalline hydrate of the composition Ho(NO3)3•5H2O.[3]
Chemical properties
[edit]Hydrated holmitic nitrate thermally decomposes to form HoONO
3 and decomposes to holmium oxide upon subsequent heating.
Application
[edit]The compound is used for the production of ceramics and glass.
Also used to produce metallic holmium and as a chemical reagent.
