LUTETIUM
Natural Abundance, Stable Isobars Lu175, 97.4%, Yb176 aLu176, 2.6%, Hf176 The only compound which has been used in the separation of lutetium isotopes is anhydrous lutetium trichloride. The average charge consists of 150 g LuCl3 in a style C-16 graphite charge bottle. The method of charge preparation and the recycle and recovery procedures developed for samarium are used for all rare earth elements with the exception of cerium. The rare earth techniques are described in detail only for samarium and cerium. Lu176 is radioactive with a half-life of 4.6 x 1010 years. |
