Abstract: The effects of sintering temperature on the microstructure and piezoelectric properties of
Pb(Mn1/3Sb2/3)O3-PbZrO3-PbTiO3 (PMS-PZT) ceramic were investigated. Results show that the optimized properties of εr=1530,
d33=374pC/N, Kp=0.6, tanδ=0.41%, Qm=1250 can be obtained when the ceramic sintered at 1240℃ for 2h, which suit for high-power applications. Meanwhile, the ceramic also possesses
superior characteristics (εr=1370, d33=348pC/N, Kp=0.57, tanδ=0.62% and Qm=1620) for multilayer components and thick-film devices when it sintered at 1150℃.
Results also indicate that PMS-PZT ceramic can be sintered in a wide temperature range. High temperature microscope, SEM, TEM, and EDS
investigation confirm that PbO and Sb_2O_5 can form a liquid phase acting as a secondary phase on grain boundaries at lower sintering
temperature, and then enter the crystal lattice to form perovskite structure at higher sintering temperature.
