Abstract
In this study, to develop the low temperature sintering ceramics for multilayer piezoelectric transformer, PSN-PNN-PZT system ceramics were manufactured as a function of CuO addition. Its dielectric and piezoelectric characteristics were investigated. With increasing the amount of CuO addition, grain size was increased and density increased until 0.3wt% CuO. Taking into consideration electromechanical coupling factor(kp) of 0.53, mechanical quality factor(Qm) of 423 and
