Electrical Properties of Cubic, Stabilized, Single ZrO2–Gd2O3 Crystals

Abstract
Electrical properties of single‐crystal, cubic ZrO2 solid solutions containing 10.0, 12.5, and 15.0 mol% Gd2O3 were investigated. Electrical conductivities were measured by a two‐terminal ac technique up to 831°C in air, and the observed data were compared with those reported for polycrystalline materials. Electrical conductivity and activation energy increased, and preexponential factor decreased with Gd2O3 content.
