Lutetium is the last of the
series of the lanthanide elements and it is a chemical element with
the symbol Lu and atomic number is 71. It was isolated
separately & independently by two chemists, Welsbach and Urbain.
Common compounds of lutetium
are lutetium aluminium garnet, lutetium bromide, lutetium chloride,
lutetium fluoride, lutetium iodide, lutetium oxide, lutetium
It is a silvery white rare
earth metal and it is also one of the least abundant lanthanides,
however it is still more abundant on earth than silver or gold.
Lutetium is not found
free in nature but is found in a number of minerals, mainly monazite
and the Pit also produced by the reduction of the anhydrous
fluoride with calcium metal.
Because the Lutetium is
radioactive, you will be radioactive for a while after the
The rare earth element
lutetium contains the isotope Lu-176 with 3,6*10 power 10 years
half-life and a natural abundance of 2,6%,which yields a specific
activity of the pure element lutetium of about 50 Bq/g.
The heavy lanthanide
lutetium is among the few elements with differences larger than 0.3
It occurs in small amounts
in minerals containing other rare earth elements, such as
bastnasite, xenotime and euxenite.
Lutetium Phosphide is a
semiconductor which has use in high power, high frequency
applications and also in laser diodes.
Lutetium is the heaviest and
hardest of the Rare Earth elements and has the highest melting point
within this group. It is rare and trades at a high price but has few
It is primarily obtained
through an ion exchange process from monazite sand a material
rich in rare earth elements.
It can be prepared by the
reduction of anhydrous LuCl3 or
an alkali or alkaline earth metal. The metal is silvery white and
relatively stable in air.
When lutetium silicate is
doped with cerium, these ions occupy the positions of lutetium.
