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(IV) oxide is used to polish glass and is an important part of catalytic converters. 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.
