Application
Cerium Metal is applied in steel foundries industry for making FeSiMg alloy and it is used as an additive for hydrogen storage alloy. Cerium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, and discs. Cerium metal is sometimes added to Aluminum to improve Aluminum's corrosion resistance.
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.
