Abstract

Self-diffusion coefficients for chloride ion were measured as a function of chloride ion capacity in solutions of varying acdity using particles of hydrous ceric oxide heated at 50, 200 and 400°C. The measured self-diffusion coefficients are dependent only upon the total chloride ion capacity. At the same capacity, self-diffusion coefficients are almost the same for ceria particles heated at different temperatures. The trace component diffusion coefficients of chloride ion in the nitrate-form of the oxide, dried at 50°C, were also measured. Under the same conditions, the self-diffusion coefficients are somewhat higher or close to the trace component diffusion coefficient for the sample dried at 50°C.
