Lutetium (Lu) Metal Application

Lutetium Metal is the hardest metal of the rare earth, used as an important additive to some specialty alloys. 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 into various shapes of ingots, pieces, wires, foils, slabs, rods, discs, and powder.

Lutetium usually occurs in association with the element yttrium and is sometimes used in metal alloys and as a catalyst in various chemical reactions. 177Lu-DOTA-TATE is used for radionuclide therapy (see Nuclear medicine) on neuroendocrine tumors.
