| Abstract(in English) | Obtaining the samples having the same microstructure but different composition by adjusting the firing temperature was investigated in BaTiO_3-MgO-Rare-earth system. The sample containing Dy showed a larger rate of grain growth than that containing Ho. The sample containing Dy fired at 1240℃ (D124) and that containing Ho fired at 1300 (H130) showed the same mean grain size and the grain size distribution determined by the observation with a scanning electron microscope. Moreover, the transmission electron microscopy observation and the differential scanning calorimetry revealed that both samples, i.e. D124 and H130, had the identical "Core-Shell" structure. Comparison of the electrical properties, such as the temperature dependence of the dielectric constant, the aging characteristics of the dielectric constant under a dc-bias field, and the mean time to failure under a highly accelerated life test were examined. It was concluded that the above electrical properties were determined by the microstructure but not by the chemical composition in this system. |
