Lutetium
(Lu) Metal |
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.

Applications
--- 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. |
