Abstract

In this study, in order to develop the low temperature sintering ceramics for multilayer piezoelectric transformer, PCW-PMN-PZT ceramics added with Li$_2$CO$_3$, Bi$_2$O$_3$ and CuO as sintering aids were manufactured, and their microstructural, dielectric and piezoelectric properties were investigated. When the only CuO was added, specimens could not be sintered below 98$0^{\circ}C$. However, when Li$_2$CO$_3$ and Bi$_2$O$_3$ were added, specimens could be sintered below 98$0^{\circ}C$. Li$_2$CO$_3$ and Bi$_2$O$_3$ addition were proved to lower sintering temperature of piezoelectric ceramics due to the effect of Li$_2$O-Bi$_2$O$_3$ liquid phase. Li$_2$CO$_3$ and Bi$_2$O$_3$ added specimens showed higher piezoelectric properties than those of the only CuO added specimens. At 0.2 wt% Li$_2$CO$_3$ and 0.3 wt% Bi$_2$O$_3$ added specimen sintered at 92$0^{\circ}C$, the dielectric constant of 1457, electromechanical coupling factor of 0.56 and mechanical quality factor of 1000 were shown, respectively. These values are suitable for multilayer piezoelectric transformer application.
