| 摘 要： | CuO added Pb_(0.92)Sr_(0.06)Ba_(0.02)(Mg_(1/3)Nb_(2/3))_(0.25)(Ti_(0.53)Zr_(0.47))_(0.75)O_3 ceramics were studied to prepare high-quality multilayer piezoelectric actuators with pure Ag electrodes at 900℃. Cu O addition not only reduced the sintering temperature significantly from 1260℃ to 900℃ but also improved the ceramic density to 7.742 g/cm~3. The 0.7 wt.% Cu O added ceramic sintered at 900℃ shows the remnant polarization(P_r) of 40 μC/cm~2, 0.28% strain at 40 kV/cm, and the piezoelectric coefficient(d_(33)) of 630 pC/N. This ceramic shows a strong relaxor characteristic with a Curie temperature of 200℃. Furthermore, the 0.7 wt.% CuO added ceramic and pure Ag electrodes were co-fired at 900℃ to prepare a high-quality multilayer piezoelectric actuator with a d_(33) of over 450 pC/N per ceramic layer.
