Abstract
We describe a new experimental technique for the determination of chemical-diffusion coefficients in oxides. This method does not involve any transfer of matter through an interface. Results obtained at 971°C for various deviations for stoichiometry x of CeO 2− x are reported and compared with calculated chemical-diffusion coefficient D̃ values from other independent transport quantities obtained on the same sample. The reasonable correlation between experimental and calculated D̃ indicates that the precision of the experimental D̃ is better than 5%.
