Abstract

In this study, in order to develop low temperature sintering ceramic ultrasonic nozzle, single-layer and multilayer ring-type piezoelectric vibrators were manufactured using PMN-PNN-PZT ceramics, And then the electrical properties were investigated. The piezoelectric vibrator were sintered at low temperature of $940^{\circ}C$. The resonant resistance decreased with the increases of the number of layer. And also, the capacitance increased with the increases of the number of layer. The mechanical quality factor (Qm) decreased with the increases of the number of layer.
