)PZT ceramics have mainly tetragonal structure confirmed by X-ray diffraction measurement and Raman spectroscopy, which is affected by composition and sintering condition. Broad dielectric peaks appear in all samples, and diffusive phase transition and dielectric frequency dispersion are obvious as well. The 0.20BNT–0.05BF–0.75PZT ceramics exhibit large piezoelectricity
