Thulium(III) nitrate is an inorganic compound, a salt of thulium and nitric acid with the chemical formula Tm(NO3)3.[1][2][3] The compound forms dark-green crystals, readily soluble in water, also forms crystalline hydrates.
Synthesis
[edit]Reaction of thulium and nitric acid:[4]
- Tm 6 HNO3 → Tm(NO3)3 3 NO2 3 H2O
Reaction of thulium hydroxide and nitric acid:
- Tm(OH)3 3 HNO3 → Tm(NO3)3 3 H2O
Physical properties
[edit]Thulium(III) nitrate forms dark-green hygroscopic crystals.
Forms crystalline hydrates of the composition Tm(NO3)3·5H2O.[5][6]
Soluble in water and ethanol.[7]
Chemical properties
[edit]Both the compound and its crystalline hydrate decompose on moderate heating.
Hydrated thulium nitrate thermally decomposes to form TmONO3 and decomposes to thulium oxide upon further heating.
Applications
[edit]Thulium(III) nitrate hydrate is used as a reagent. Also used in optical glasses, ceramics, catalysts, electrical components, and photo-optical materials.[8]
