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]
