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.
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]
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]
