摘要：
Li2CO3-doped 15PSN-52PMN-33PT (PSN-PMN-PT-xwt%Li2CO3) piezoelectric ceramics were successfully synthesized at 1100 °C by the two-step columbite precursor method. Their microstructure, dielectric, ferroelectric, and piezoelectric properties were systematically investigated. The optimum comprehensive electrical properties are achieved in 0.5 wt% Li2CO3-modified PSN-PMN-PT ceramic: Tr−t = 126 °C, Tc = 180 °C, d33 = 520 pC/N, kp = 0.62, Ec = 5.1 kV/cm, and Pr = 33.6 µC/cm2. These results indicate that low-temperature-sintered Li2CO3-doped PSN-PMN-PT ceramics are promising candidates for piezoelectric device applications.
