Production

Lutetium(III) fluoride can be produced by reacting lutetium oxide with hydrogen fluoride, or reacting lutetium chloride and hydrofluoric acid:[3]

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:[4]

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.[5]
