Cerium monosulfide is a binary inorganic compound of cerium and sulfur with the chemical formula CeS. This is the simplest of cerium sulfides.




Synthesis


Heating stoichiometric amounts of pure substances at 2450 °C:
Ce + S → CeS
Reduction reaction of dicerium trisulfide and cerium hydride:
Ce2S3 + CeH2 → 3CeS + H2




Physical properties


Cerium sulfide forms yellow crystalline solid of cubic syngony crystals, space group Fm3m, cell parameter a = 0.5780 nm, Z = 4, of NaCl-type structure.
The compound melts congruently at a temperature of 2450 °C.




Chemical properties


Cerium monosulfide has a wetting effect on metals, and it is relatively stable to metals other than platinum. It can react violently with platinum to form an intermetallic compound, platinum cerium.
