Application---
Lutetium Metal, is the hardest metal of the rare-earths, used as important additive to some specialty alloy.One commercial application has been as a pure beta emitter, using lutetium which has been exposed to neutron activation. A tiny amount of lutetium is added as a dopant to gadolinium gallim garnet (GGG), which is used in magnetic bubble memory devices.

Pure metal lutetium has been isolated only in recent years and is one of the more difficult to prepare. It can be prepared by the reduction of anhydrous LuCl₃ or LuF₃ by an alkali or alkaline earth metal. The metal is silvery white and relatively stable in air. It is the hardest and the densest of the lanthanides.
