摘　　要：In this work,Li_(2)O_(3)was added into 0.7BiFeO_(3)-0.3BaZr_(0.02)Ti_(0.98)O_(3)-0.01molMnO_(2)(70BFBTMn)piezoelectric ceramics to reduce their sintering temperatures.70BFBTMn ceramics were sintered by a conventional solid reaction method,and their structural,dielectric,piezoelectric and ferroelectric properties were studied.These results indicate that 0.5%(mole)Li_(2)O_(3)is the optimized content and it can reduce the sintering temperature by 100°C,making the possibility of the piezoelectric ceramics cofiring with Ag electrodes at low temperatures to manufacture multilayer piezoelectric actuators.
