Characteristic
Cerium is a chemical element with the symbol Ce and atomic number 58. Cerium is a soft, ductile and silvery-white metal that tarnishes when exposed to air, and it is soft enough to be cut with a knife.
Phase at STP： solid
Melting point： 1068 K (795 °C, 1463 °F)
Boiling point： 3716 K (3443 °C, 6229 °F)
Density (near r.t.)： 6.770 g/cm3
when liquid (at m.p.)： 6.55 g/cm3
Heat of fusion： 5.46 kJ/mol
Heat of vaporization： 398 kJ/mol
Molar heat capacity： 26.94 J/(mol·K)
Application
Cerium metal is used in ferrocerium lighters for its pyrophoric properties. Cerium-doped YAG phosphor is used in conjunction with blue light-emitting diodes to produce white light in most commercial white LED light sources.
