摘要: CuO added Pb0.92Sr0.06Ba0.02(Mg1/3Nb2/3)0.25(Ti0.53Zr0.47)0.75O3 ceramics were studied to prepare high-quality multilayer piezoelectric actuators with pure Ag electrodes at 900℃. CuO addition not only reduced the sintering temperature significantly from 1260℃ to 900℃ but also improved the ceramic density to 7.742 g/cm3. The 0.7 wt.% CuO added ceramic sintered at 900℃ shows the remnant polarization (Pr) of 40 μC/cm2, 0.28% strain at 40 kV/cm, and the piezoelectric coefficient (d33) 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 d33 of over 450 pC/N per ceramic layer.

关键词: piezoelectric ceramics, low-temperature co-fired ceramic, multilayer piezoelectric actuators
