Reaction of thulium and nitric acid:
Reaction of thulium hydroxide and nitric acid:
Thulium(III) nitrate forms dark-green hygroscopic crystals.
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.
Thulium(III) nitrate hydrate is used as a reagent. Also used in optical glasses, ceramics, catalysts, electrical components, and photo-optical materials.
