Lutetium Use and Manufacturing
Lutetium 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 Metal, is the hardest metal of the rare-earths, used as important additive to some specialty alloy. Stable Lutetium can be used as catalysts in petroleum cracking in refineries and can also be used in alkylation, hydrogenation, and polymerization applications. Lutetium is used as a phosphor in LED light bulbs. Lutetium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder.
