Cerium monosulfide is a binary inorganic compound of cerium and sulfur with the chemical formula CeS.^[1]^[2]^[3]^[4] 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:^[5]

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.^{[citation needed]}

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.^[5]
