The grain growth studies presented here show anomalies in the growth dynamics in SrTiO3. For the temperature range investigated, the overall grain growth does not follow the classical Arrhenius-type temperature dependence. At a critical temperature the grain growth rate decreases substantially with increasing temperature. Such a decrease is reported for the first time in bulk ceramic material.
