B-site cation inter-diffusion in yttrium substituted barium zirconate

Journal of Materials Chemistry A, vol. 9, pp. 21142–21150

Abstract

This study of B-site cation inter-diffusion in the bulk and grain-boundary of the ceramic proton conductor yttrium-substituted barium zirconate (BZY) show that BZY electrolytes are highly stable towards degradation related to B-site cation diffusion.
