Lutetium(III) fluoride

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

Production

Lutetium fluoride can be produced by reacting lutetium oxide with hydrogen fluoride, or reacting lutetium chloride and hydrofluoric acid:
It can also be produced by reacting lutetium sulfide and hydrofluoric acid:
Lutetium oxide and nitrogen trifluoride react at 240 °C to produce LuOF. A second step happens below 460 °C to produce LuF₃.
