Abstract
SOLID oxide electrolytes with predominantly oxide ion (O2−) conductivity should show isotope effects resulting from the different mobilities of 16O, 17O and 18O through the anion sub-lattice. In particular, the oxygen-containing gas stream leaving the cathode of an oxide electrolyte cell should be enriched in the heavier isotopes because of the greater mass and consequent lower mobility of 17O and 18O. This principle has already been suggested as a means of separating the heavier isotopes1 and we now describe experiments which were undertaken to examine the magnitude of its effect.
