Abstract

This work is concerned with phase formation and cation interdiffusion in the GdxCe1-xO2-x/2 and SmxCe1-xO2-x/2 systems at temperatures below 1200°C. Diffusion-couple samples were fabricated and used in this work, which are well suited to analyze phase formation and to determine cation interdiffusion coefficients. The samples consist of CeO2 substrates with a thin film of Sm2O3 and Gd2O3, respectively, deposited on the substrates. CeO2 substrates with low porosity and impurity concentration were fabricated from high-purity CeO2 powder.
