摘要

•A synergetic strategy including introducing lead vacancies and constructing an MPB to improve the piezoelectricity and temperature stability.•Excellent piezoelectric properties (d33=864 pC/N, kp=84%, TC=201 °C) are obtained simultaneously in PBZTN-0.540 ceramics.•High temperature stability (less than 10% variations for electrical properties from 20 °C to 160 °C) is achieved in PBZTN-0.540 ceramics.
