Trivalent Ion Exchange in Beta' Alumina.
Abstract
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.
