Via composition designing and sintering condition tailoring, high-density pure perovskite structure x Bi(Ni 0.50 Ti 0.50 )O 3 –0.05BiFeO 3 –(0.95− x )Pb(Zr 0.50 Ti 0.50 )O 3 [ x BNT–0.05BF–(0.95− x )PZT, x = 0.19, 0.20, 0.21, 0.22, 0.23] ceramics were prepared by solid-state sintering method with adding additional 0.5 wt% LiBO 2 sintering aid, whose sintering temperature was lower than that reported in literature. The x BNT–0.05BF–(0.95− x )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 d 33 = 386 pC/N combined with rather high dielectric constant maximum temperature T m = 264°C, presenting enormous application potential in the high-temperature piezoelectric-related field.
