N2 - PZT-based perovskite structure relaxors are very attractive for high power piezoelectric applications. Targeting multilayer co-fired piezoelectric transformers, we developed a PNN-PMW-PZT system [Pb(Ni1/3Nb2/3)O3-Pb(Mg1/2W1/2)O3-0.9Pb(Zr0.5Ti0.5)O3+xMnO2] and used flux materials to decrease the sintering temperature. Systematically investigating the effect of MnO2 content on piezoelectric and dielectric properties, the composition with 0.25 wt% MnO2 hardener exhibited excellent piezoelectric properties after sintering at 1000 °C for 2 h (Qm: 1150, kp: 0.63, d33: 345, tan δ: 0.0040, εT 33/ε0: 1030). In addition to the compositional development, this work also involved functional tests and high-power characterization of a multilayer piezoelectric transformer utilizing this new ternary system that provided 38 W/cm3 output power density with 92% efficiency and a step-up ratio of 7.
