Ytterbium(III) sulfide is a binary inorganic compound of ytterbium and sulfur with the chemical formula Yb2S3.[1]

Preparation

[edit]

Ytterbium(III) sulfide can be obtained by reacting ytterbium and sulfur in an inert atmosphere at 450–800 °C:

2Yb + 3S → Yb2S3

It can also be prepared by passing hydrogen sulfide through heated ytterbium(III) oxide:

Yb2O3 + 3H2S → Yb2S3 + 3H2O

Physical properties

[edit]

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]

Uses

[edit]

The compound is used in the production of ceramics and as a catalyst.[3]
