Lutetium(III) fluoride

Lutetium(III) fluoride is an inorganic compound with a chemical formula LuF₃.

Production

Lutetium(III) fluoride can be produced by reacting lutetium oxide with hydrogen fluoride, or reacting lutetium chloride and hydrofluoric acid:

Lu₂O₃ + 6 HF → 2 LuF₃ + 3 H₂O

LuCl₃ + 3 HF → LuF₃ + 3 HCl

It can also be produced by reacting lutetium sulfide and hydrofluoric acid:

3 Lu
₂S
₃+ 20 HF + (2 + 2x) H
₂O → 2 (H
₃O)Lu
₃F
₁₀·xH
₂O↓ + 9 H
₂S↑ (x = 0.9)

(H₃O)Lu₃F₁₀ → 3 LuF₃ + HF↑ + H₂O↑

Lutetium oxide and nitrogen trifluoride react at 240 °C to produce LuOF. A second step happens below 460 °C to produce LuF₃.
