Production

Lutetium(III) fluoride can be produced by reacting lutetium oxide with hydrogen fluoride,or reacting lutetium chloride and hydrofluoric acid:[7]

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:[8]

3 Lu₂S₃ + 20 HF + (2 + 2x) H₂O → 2 (H₃O)Lu₃F₁₀·xH₂O↓ + 9 H₂S↑ (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.[9]
