Dunn, B; Farrington, G C

Ion exchange techniques were used to substitute trivalent cations for the sodium ions present in sodium beta alumina single crystals. Complete replacement was achieved using Gd3+, Nd3+, and Eu3+ ions in molten salts. The conductivity of Gd3+ beta alumina was measured and optical properties of Nd3+ exchanged materials were studied. The trivalent beta aluminas appear to be the first solid electrolytes to exhibit rapid trivalent cation motion at moderate temperatures.
