Abstract

In this study, in order to develop low temperature sintering ceramics for multilayer piezoelectric actuator application. At the PMN-PZN-PZT ceramics, the influence of the ball-mill time on piezoelectric characteristics was investigated. All the specimens improved according to the increase of the ball-mill time increase. The specimen showed the optimum value when ball-mill time is 60 hour. Their optimum values were density=$7.93g/m^3$, ${\varepsilon}_r=1371$, kp=0.551, Qm=1609, $d_{33}=321pC/N$, respectively.
