N2 - Pb(Zr,Ti)O3-Pb(Fe2/3W1/3)O3-Pb(Mn1/3Nb2/3)O3 (PZT-PFW-PMN) quaternary piezoelectric ceramics using CeO2 and excess Pb3O4 as additives were fabricated by the addition of LiSbO3 as a sintering aid. The effects of LiSbO3 contents and sintering temperature on the phase structure, density, dielectric and piezoelectric properties of ceramics were investigated. It was observed that the addition of LiSbO3 not only decreased the sintering temperature from 1200 to 930 °C but also optimized the properties. Temperature dependence of dielectric and piezoelectric properties of PZT-PFW-PMN ceramics with LiSbO3 addition were studied at a temperature range from room temperature to 290 °C. It was found that the anti-resonant frequencies (fa) decreased with increasing temperature but the trend was reversed for resonant frequency (fr) which was related to the increased domain activities at higher test temperatures. Piezoelectric constant (d33) was finally found to decrease with increasing temperature. The result showed that 0.10 wt.% LiSbO3-modified ceramics sintered at 930 °C exhibited favorable properties, which were listed as follows: d33 = 363 pC/N, Kp = 0.60, Qm = 749, εr = 1596, Tc = 286 °C, Pr = 14.84 μm/cm-2 and Ec = 11.06 kV/cm, which make this system be a promising material for multilayered piezoelectric actuator and sensor applications.
