Abstract

BaTi1-xCaxO3-x ceramics, where 0≤x≤0.04, prepared by the mixed oxide route at 1500 °C display a strong suppression of the Curie temperature and a significant increase in grain conductivity with increasing x. The ramifications of these results on the applicability of using Ca2+ as a dopant to achieve X8R specification in BaTiO3-based formulations are discussed.
