Formation of BaTiO 3 ‐SrTiO 3 solid solution during sintering of powder mixtures is characterized by preferential diffusion of Ba 2+ ions. As a consequence, several nonequilibrium phases are temporarily formed; they were identified by X‐ray and microprobe analysis. Eutectic liquid appears below 1300°C, which may explain exaggerated grain growth during sintering of BaTiO 3 ‐SrTiO 3 mixtures. Disturbance in neck growth and Kirkendall‐type porosity hamper densification in the heterogeneous system as compared with the pure titanates.
