ERBIUM
Natural Abundance, Stable Isobars Er162, 0.136%, Dy162 Er164, 1.56%, Dy164 Er166, 33.41%, Yb168 Er167, 22.94%, Yb170 Er168, 27.07% Er170, 14.88% The only compound which has been used in the separation of erbium isotopes is anhydrous erbium trichloride. The average charge consists of 150g ErCl3 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. |
