Abstract

The Na_0.325Bi_0.395Sr_{0.245□0.035}TiO₃ + x % MnCO₃ (NBST-100xMn) lead-free ceramic samples had been fabricated by solid-state reaction method. Microstructure and electrical properties with the addition of MnCO₃ had been studied in detail. The NBST-4Mn showed a low hysteresis behavior with the maximum electrostrictive coefficient (Q) of 0.0294 m⁴/C² and the recoverable energy storage density (W_rec) of 1.3 J/cm³ at 95 kV/cm. In addition, the electrostrictive effect and energy storage ability presented outstanding temperature stability and fatigue resistance, which indicated a promising lead-free ceramic for high precise actuator.
