Infobox references

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]
Ce
2
S
3
+ CeH
2
→ 3CeS + H
2

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]
