Cerium Monosulfide
Cerium monosulfide is a binary inorganic compound of cerium and sulfur Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula ... with the chemical formula CeS. This is the simplest of cerium sulfides. Synthesis * Heating stoichiometric amounts of pure substances at 2450 °C: :: * Reduction reaction of dicerium trisulfide and cerium hydride: :: 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
