Abstract A near morphotropic phase boundary composition 0.37BF-0.31PMN-0.31PT has been synthesized using the conventional solid-state reaction method. Scanning electron microscopy revealed a dense microstructure of the ternary ceramic system. A high piezoelectric coefficient (d33* = 572 pm/V) was revealed from the displacement-voltage curve (butterfly loop). An excellent pyroelectric response was displayed by the ceramic in the temperature range of 30–80 °C. Good saturated ferroelectric loops with good fatigue resistant characteristic and high value of remanent polarization (Pr = 60.62 μC/cm2) and coercive field (Ec = 18.77 kV/cm) were obtained for the synthesized ceramic. Apart from the conventional method used for reporting the Pr value, which is normally larger than the practically usable (remanent) polarization component, true-remanent hysteresis task was used to isolate the non-remanent component and hence reveal the true-remanent component of polarization which was found to be ~ 80% that of the conventional Pr value suggesting low leakage contributions in the ternary ceramic system. Time-dependent compensated hysteresis task was performed to study the resistive-leakage nature of the ceramic, which is a frequency dependent parameter.

0.37BF-0.31PMN-0.32PT：MPB 的优质压电/热解/铁电三元陶瓷

摘要 使用常规固相反应方法合成了一种近同形相界成分0.37BF-0.31PMN-0.31PT。扫描电子显微镜揭示了三元陶瓷系统的致密微观结构。从位移-电压曲线（蝴蝶环）显示出高压压电系数（d33* = 572 pm/V）。陶瓷在 30-80°C 的温度范围内显示出优异的热电响应。合成陶瓷获得了具有良好抗疲劳特性和高剩余极化值 (Pr = 60.62 μC/cm2) 和矫顽场 (Ec = 18.77 kV/cm) 的良好饱和铁电回路。除了用于报告 Pr 值的常规方法外，Pr 值通常大于实际可用的（剩余）偏振分量，真剩磁迟滞任务用于隔离非剩磁分量，从而揭示极化的真剩磁分量，发现其为传统 Pr 值的约 80%，表明三元陶瓷系统中的泄漏贡献较低。执行时间相关补偿滞后任务以研究陶瓷的电阻泄漏特性，这是一个频率相关参数。
