The microstructure and piezoelectric, ferroelectric, and dielectric properties were investigated, with a special emphasis on the influence of sintering temperature from 1,100 to 1,140°C. Orthorhombic phases mainly exist in the ceramics sintered at 1,100-1,130°C, whereas the tetragonal phase becomes dominant when sintering temperature is above 1,130°C. Because of the existence of MPB-like transitional behavior, the piezoelectric coefficient (d 33), electromechanical coupling coefficient (kp), and dielectric constant (ε) show peak values of 304pC/N, 0.48, and 1,909, respectively, which are obtained in the sample sintered at 1,120°C, and its Curie temperature (T C) is about 271°C.
