Abstract

We have investigated the influence of Ti/Ba mole ratio in the characteristics of the modified $BaTiO_3$ systems with Ca addition. The specimens were fabricated with variations in Ti/Ba mole ratio between 0.995 and 1.01, and sintered in the temperature range between $1325^{\circ}C$ and $1375^{\circ}C$. When Ti/Ba mole ratio was 1.005 and sintering temperature was $1350^{\circ}C$, the breakdown voltage shows 260[V /mm].
