Ytterbium(III) sulfide is a binary inorganic compound of ytterbium and sulfur with the chemical formula Yb2S3. [1]
Ytterbium(III) sulfide can be obtained by reacting ytterbium and sulfur in an inert atmosphere at 450–800 °C:
It can also be prepared by passing hydrogen sulfide through heated ytterbium(III) oxide:
Ytterbium(III) sulfide forms yellow crystals of rhombic symmetry, and cell parameters a = 0.678 nm, b = 0.995 nm, c = 0.361 nm. [2]
This salt is used in the production of ceramics and as a catalyst. [3]
