Abstract

The piezoelectric properties of Pb(Mn_1/3Sb_2/3)_0.05Zr_xTi_yO₃(PMS-PZT) ceramics were systematically investigated by varying the Zr/Ti ratio and analyzing the role of defect dipoles in the microstructure and electrical properties. Experimental results reveal that adjusting the Zr/Ti ratio affects the grain size, oxygen vacancy concentration, and ferroelectric domain structure of the ceramics, thereby modulating the piezoelectric constant (d₃₃), mechanical quality factor (Q_m), and dielectric loss (tanδ) of the material. Significantly, the PMS-PZT ceramics with Zr/Ti of 47.5/47.5 show excellent temperature stability: the PMS-PZT ceramics retain more than 86% of their maximum piezoelectric constants at temperatures around 270 °C, and have loss tangent (tanδ) of less than 0.3% Furthermore, a weakening of the defect dipole pinning effect was observed, leading to a significant increase in the remanent polarization of the material. The variation of the current-electric field profile and Polarization–Electric field hysteresis loop with temperature is illustrated from the point of view of the ferroelectric domain switching.

通过改变 Zr/Ti 比，系统研究了 Pb(Mn1/3Sb2/3)0.05ZrxTiyO3(PMS-PZT)陶瓷的压电特性，并分析了缺陷偶极子在微结构和电特性中的作用。实验结果表明，调整 Zr/Ti 比会影响陶瓷的晶粒尺寸、氧空位浓度和铁电畴结构，从而调节材料的压电常数 (d33)、机械品质因数 (Qm) 和介电损耗 (tanδ)。值得注意的是，Zr/Ti 为 47.5/47.5 的 PMS-PZT 陶瓷显示出卓越的温度稳定性：PMS-PZT 陶瓷在 270 °C 左右的温度下仍能保持其最大压电常数的 86% 以上，并且损耗正切（tanδ）小于 0.3%。从铁电场畴切换的角度说明了电流-电场曲线和极化-电场滞后环随温度的变化。
