Thullium(III) fluoride is an inorganic compound with the chemical formula TmF₃.

Production

It can be produced by reacting thulium(III) sulfide and hydrofluoric acid, followed by thermal decomposition:[1]

3 Tm₂S₃ + 20 HF + (2 + 2x)H₂O → 2 (H₃O)Tm₃F₁₀·xH₂O↓ + 9 H₂S↑ (x=1.7)

(H₃O)Tm₃F₁₀ → 3 TmF₃ + HF↑ + H₂O↑

Thulium(III) oxide reacts with fluorinating agents such as hydrogen fluoride,[2] nitrogen trifluoride[3] xenon difluoride[4] to create thullium(III) fluoride as well, although the reaction with nitrogen trifluoride is incomplete and produces a mixture of TmOF and TmF₃.[3]

gollark: styropyro in the year 2400

gollark: I duckduckgoed myself, and I found a Twitter account of someone in the US with the same name who just retweets random political stuff, a consultant company of some sort named "[REDACTED] & Associates", a page for someone working at "ZDNet", a Wikipedia article and a LinkedIn page. Weird.

gollark: Could you put a thin layer of glass on top of plastic, or would that be a "problems of both, benefits of neither, exciting new problems too" kind of situation?

gollark: Actually, how come tempered glass is used instead of plastic, which would *not* randomly explode as far as I know? Strength?

gollark: Great, you've made me scared of shower doors, at least until I inevitably forget that.
