N2 - In this study, the sintering characteristics of 0.69Pb(Zr0.47Ti0.53)O3-0.31Pb[(Zn0.4Ni0.6)1/3Nb2/3] (PZT-PZNN) ceramics after the addition of LiBiO2 were studied. This addition lowered the sintering temperature from 1150 to 900 °C. The crystal structure changed from tetragonal to rhombohedral as the additive content increased by 0.7%. The polarization of the sintered specimen was conducted at an electric field of 3 kV/mm. When 0.7 wt% of LiBiO2 was added and sintered at 900 °C, the piezoelectric constant (d33) was 602 pC/N; moreover, the electromechanical coupling coefficient (kP), sintered density, and Curie temperature (Tc) at 1 kHz were 66.3%, 7.99 g/cm3, and 252.8 °C, respectively. When 0.7 wt% of LiBiO2 was added, the PZT-PZNN ceramic showed an increased strain curve of 0.118% at 2 kV/mm. The interdiffusion between the copper (Cu) electrode and ceramic material was not observed in the scanning electron microscopy (SEM) results; thus, the possibility of manufacturing an actuator using a Cu electrode using a novel composition was confirmed. The actuator displacement with the voltage 400 V was 1.2 μm. The thickness of the multi-layered actuator was 1 mm. Through this, the possibility of manufacturing a multi-layered actuator with a Cu electrode was confirmed through the composition of 0.69PZT-0.31PZNN (LiBiO2 0.7 wt%).
