초록

In this study, in order to develop the composition of ceramics capable of being sintered at low temperature with high piezoelectric properties, PZW-PMN-PZT system ceramics for piezoelectric energy harvesting application were manufactured according to the amount of PZW addition. And also, their microstructural, dielectric and piezoelectric properties were investigated. At the sintering temperature of $930^{\circ}C$, a 5 mol% PZW substituted specimen showed a maximum value of density = $7.905g/cm^3$, kp = 0.585, $d_{33}$ = 351pC/N and Qm =1,254, respectively.
