Abstract

BaZr_{1 - x}Y_xO_{3 - δ} is a proton-conducting oxide that has both high ionic conductivity and good chemical stability, but disadvantageously has low sinterability. In this work, two co-dopant systems, BaZr_0.9(Y_{1 - x}M_x)_0.1O_{3 - δ} (M = Ga, In), were studied with the aim of improving sinterability. In both systems, sinterability was markedly improved. Although the addition of Ga markedly decreased the conductivity of BaZr_{1 - x}Y_xO_{3 - δ}, the addition of In did not decrease the conductivity significantly. It was shown that BaZr_0.9Y_0.05In_0.05O_{3 - δ} is a practically useful material with a good combination of conductivity and sinterability.
