Abstract

Space charge contributions to the densification of perovskite ceramics during sintering were assessed in the model system strontium titanate using a combined experimental and analytical approach. Defect chemistry in the bulk and at the grain-boundaries for SrTiO? in high temperature regions were calculated based on literature data. Diffusion coefficients for bulk-diffusion and grain boundary-diffusion were estimated and used with Coble’s equations for densification rates.
