Abstract: The effects of MnO2 addition on the sintering temperature, microstructure, dielectric, piezoelectric properties and the temperature stability of PbZrO3-PbTiO3-Pb(Fe2/3W1/3)O3-Pb(Mn1/3Nb2/3)O3-BiFeO3 (PZT-PFW- PMN-BF) ceramics were investigated. The 0.10 wt% MnO2-added PZT-PFW-PMN ceramics sintered at 950℃ exhibited the favorable piezoelectric and dielectric properties, which were listed as follows: ρ=7.78 g/cm3, d33=394 pC/N, Kp=0.54, Qm=1180, εr=1480, △fr/fr25℃=1.68 % and △Kp/Kp25℃=-1.06 %, respectively.

Key words: piezoelectric ceramics, low sintering temperature, electrical properties
