OtherSolid|Liquid

Lanthanum(2+) is a lanthanum molecular entity, a monoatomic dication and a divalent metal cation.|Lanthanum is a silvery white metallic element that belongs to period 6 of the lanthanoids family, with phosphate binding property. Lanthanum, when administered in a salt form, dissociates in acid to release lanthanum ions, which then bind dietary phosphate. This agent inhibits the absorption of phosphate by forming highly insoluble lanthanum-phosphate complexes that reduce concentrations of serum phosphate and calcium phosphate.|The prototypical element in the rare earth family of metals. It has the atomic symbol La, atomic number 57, and atomic weight 138.91. Lanthanide ion is used in experimental biology as a calcium antagonist; lanthanum oxide improves the optical properties of glass.

Lanthanum Use and Manufacturing

Uses

Lanthanum is the first element in the rare earth or Lanthanide series. It is the model for all the other trivalent rare earths. After Cerium, it is the second most abundant of the rare earths.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.
