The invention discloses a high-performance potassium-sodium niobate series lead-free electrostrictive ceramic and a preparation method and application thereof. The lead-free piezoelectric ceramic is represented by a general formula [(K0. 5Na0. 5) 1-x-Bix] (Nb1-(2/3) x-Ni (2/3) x) O3, and x is greater than or equal to 0.03 and less than or equal to 0.07. The lead-free electrostrictive ceramic prepared by the method has good electrostrictive coefficient and temperature stability; the electrostriction coefficient can reach 0.0456 m4/C2, the electrostriction coefficient is kept stable in a wide temperature range from room temperature to 180 DEG C, the lead-free electrostrictive ceramic can be applied to electronic devices such as drivers and micro-displacement controllers, and the lead-free electrostrictive ceramic has great significance in replacing the lead-based electrostriction material.
本发明公开了一种高性能铌酸钾钠系无铅电致伸缩陶瓷及其制备方法与应用，该无铅压电陶瓷由通式[(KNa)‑Bi](Nb‑Ni)O表示，式中0.03≤x≤0.07。本发明所制备的无铅电致伸缩陶瓷具有良好的电致伸缩系数和温度稳定性，其致伸缩系数可达0.0456m/C，电致伸缩系数在室温至180℃的宽温区内保持稳定，可在驱动器和微位移控制器等电子器件中获得应用，对取代铅基电致伸缩材料具有重大意义。
