GADOLINIUM
Natural Abundance, Stable Isobars Gd152, 0.20%, Sm152 Gd154, 2.15%, Sm154 Gd155, 14.73%, Dy156 Gd156, 20.47%, Dy158 Gd157, 15.68%, Dy160 Gd158, 24.87% Gd160, 21.90% The only compound which has been used in the separation of gadolinium isotopes is anhydrous gadolinium trichloride. The average charge consists of 150g GdCl3 in a style C-16 graphite charge bottle. The method of charge preparation and the recycle and recovery procedures developed for samarium is used for all rare earth elements with the exception of cerium. The rare earth techniques are described in detail only for samarium and cerium. |
