Stanford - Model ME71 -Lutetium Metal
Lutetium was the last natural rare earth element to be discovered. It is a silvery white metal which is corrosion resistant in dry air. Lutetium metal is slightly unstable in air at standard conditions, but it easily burns at 150 °C to form lutetium oxide.

Lutetium is often used as catalysts in petroleum cracking in refineries and used in alkylation, hydrogenation, and polymerization applications. Some lutetium compounds also have specific uses. For example, lutetium tantalate (LuTaO4) is the densest known stable white material (density 9.81 g/cm3) and therefore is widely used in X-ray phosphors.
