Lutetium, atomic no.71, symbol as Lu, weight at 174.97
Lutetium, atomic no.: 71, symbol as Lu, weight at 174.97, is the last member of the rare earth series. Unlike most rare earths it lacks a magnetic moment. It also has the smallest metallic radius of any rare earth. It is perhaps the least naturally abundant of the Lanthanides. It is the ideal host for x-ray phosphors because it produces the densest known white material, Lutetium Tantalate (LuTaO4). It is utilized as a dopant in matching lattice parameters of certain substrate garnet crystals, such as Indium-Gallium-Garnet (IGG) crystals due its lack of a magnetic moment. Stable lutetium can be used as catalysts in petroleum cracking in refineries and can also be used in alkylation, hydrogenation, and polymerization applications.
Lutetium OxideLutetium Oxide The important raw material for laser crystals, and also has specialized uses in ceramics, glass, phosphors, lasers. It is also used as catalysts in cracking, alkylation, hydrogenation, and polymerization.
Lutetium ChlorideLutetium Chloride Has specialized uses in optical dopant and laser crystal. And it is also be used as optical fiber
Lutetium MetalLutetium Metal The hardest metal of the rare-earths, used as important additive to some specialty alloys.
Lutetium FluorideLutetium Fluoride Used for making laser crystal, and also have specialized uses in ceramics, glass, phosphors, lasers, also be used as catalysts in cracking, alkylation, hydrogenation, and polymerization.
