Lutetium is a chemical element with the symbol Lu and atomic number 71. Because of the rarity and high price, lutetium has very few commercial uses. Stable lutetium can be used as catalysts in petroleum cracking in refineries and can also be used in alkylation, hydrogenation, and polymerization applications. It has also been used in electronics applications.
