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:[3]
- Lu
2O
3 + 6 HF → 2 LuF
3 + 3 H
2O - LuCl
3 + 3 HF → LuF
3 + 3 HCl
It can also be produced by reacting lutetium sulfide and hydrofluoric acid:[4]
- 3 Lu2S3+ 20 HF + (2 + 2x) H2O → 2 (H3O)Lu3F10·xH2O↓ + 9 H2S↑ (x = 0.9)
- (H
3O)Lu
3F
10 → 3 LuF
3 + HF↑ + H
2O↑
Lutetium oxide and nitrogen trifluoride react at 240 °C to produce LuOF. A second step happens below 460 °C to produce LuF3.[5]
