Chemical compound
Thulium(III) nitrate is aninorganic compound , a salt ofthulium andnitric acid with the chemical formulaTm(NO3 )3 .[ 1] [ 2] [ 3]
Reaction of thulium and nitric acid:[ 4]
Tm + 6 HNO3 → Tm(NO3 )3 + 3 NO2 + 3 H2 O Reaction of thulium hydroxide and nitric acid:
Tm(OH)3 + 3 HNO3 → Tm(NO3 )3 + 3 H2 O Physical properties [ edit ] Thulium(III) nitrate forms dark-green hygroscopic crystals.
Forms crystalline hydrates of the compositionTm(NO3 )3 ·5H2 O .[ 5] [ 6]
Soluble inwater andethanol .[ 7]
Chemical properties [ edit ] Both the compound and its crystalline hydrate decompose on moderate heating.
Hydrated thulium nitrate thermally decomposes to formTmONO3 and decomposes tothulium 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.[ 8]
