Lanthanum Metal and Compounds

Lanthanum, La

Atomic No.: 57

M.W.: 138.91 g/mole


 Lanthanum is the first element in the REEs or lanthanide series. It is the model for all the other trivalent rare earths. It is the second most abundant of the REE after cerium.

Lanthanum-rich lanthanide compounds have been used extensively for cracking reactions in FCC catalysts, especially to manufacture high-octane gasoline from heavy crude oil.

Lanthanum-Rich Rare Earth metals play the important roles in hydrogen storage batteries.

It is utilized in green phosphors based on the phosphate (La0.4Ce0.45Tb0.15)PO4.

Lanthanide zirconates are used for their catalytic and conductivity properties and lanthanum stabilized zirconia has useful electronic and mechanical properties.

It is utilized in laser crystals based on the yttrium-lanthanum-fluoride (YLF) composition.
