Faster grain-boundary diffusion with a higher activation enthalpy than bulk diffusion in ionic space-charge layers
Abstract
With faster (v Sr v O ) associates in the bulk and slower v Sr isolated vacancies accumulating in space-charge layers, faster grain-boundary diffusion of Sr is shown to occur with a higher activation enthalpy of diffusion than in the bulk.
