Use

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;in laser crystals based on the Yttrium-Lanthanum-Fluoride (YLF) composition. Lanthanum Metal is the very important raw materials in producing Hydrogen Storage Alloys for NiMH batteries, and is also used to produce other pure Rare Earth metals and specialty alloys. Small amounts of Lanthanum added to Steel improves its malleability, resistance to impact, and ductility; Small amounts of Lanthanum are present in many pool products to remove the Phosphates that feed algae. Lanthanum Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder.
