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
- Reduction reaction of dicerium trisulfide and cerium hydride:[5]
- Ce2S3 + CeH2 → 3CeS + H2
- Reacting cerium metal and sulfur in a planetary ball mill:[6]
- Ce + S → CeS
Physical properties
Cerium sulfide forms golden cubic crystals, with space group Fm3m and lattice parameter a = 5.763 Å. It has a NaCl-type structure.[7]
The compound melts congruently at a temperature of 2450 °C, the highest out of any known sulfide.[6]
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]
