Production

Similar to sodium sulfide, anhydrous cesium sulfide can be produced by reacting cesium and sulfur in THF. It needs ammonia or naphthalene to react.

2 Cs + S → Cs2S

By dissolving hydrogen sulfide into cesium hydroxide solution, it will produce cesium bisulfide, then it will produce cesium sulfide too.。

CsOH + H2S → CsHS + H2O
CsHS + CsOH → Cs2S + H2O
