## Synthesis

Reaction of thulium and nitric acid:[4]

Tm + 6HNO
3 → Tm(NO

3 \+ 3NO
2 \+ 3H

Reaction of thulium hydroxide and nitric acid:

Tm(OH)
3 \+ 3HNO
3 → Tm(NO

3 \+ 3H

## Physical properties

Thulium(III) nitrate forms dark-green hygroscopic crystals.

Forms crystalline hydrates of the composition Tm(NO

3 * 5H2O.[5][6]

Soluble in water and ethanol.[7]

## Chemical properties

Both the compound and its crystalline hydrate decompose on moderate heating.

Hydrated thulium nitrate thermally decomposes to form TmONO
3 and decomposes to thulium oxide upon further heating.

## Applications

Thulium(III) nitrate hydrate is used as a reagent. Also used in optical glasses, ceramics, catalysts, electrical components, and photo-optical materials.[8]
