Abstract

In this paper, the microwave dielectric properties of the yPb($Fe_{2/3}W_{1/3}$)$O_{3}$ - (1-y)($Pb_{x}Ca_{1-x}$)$ZrO_{3}$ system were investigated. It was found that an addition of Pb($Fe_{2/3}W_{1/3}$)$O_{3}$ promotes the grain growth, the solid solution between the Pb-based perovskite and the Ca-based perovskite and the decreasing of the sintering temperature. Especially, we found that 0.05Pb($Fe_{2/3}W_{1/3}$)$O_{3}$-0.95($Pb_{x}Ca_{1-x}$)$ZrO_{3}$ ceramic has not only lower sintering temperature but also better dielectric properties than those of the (Pb, Ca)$ZrO_{3}$ systems.
