Pb_0.97La_0.03(Zr_0.9Ti_0.1)_0.9925O₃ (PLZT 3/90/10) ceramics prepared by solid-state reaction with the compositions near the antiferroelectric/ferroelectric (FE/AFE) phase boundary were studied. From the polarization–electric field P(E) dependence and ex situ X-ray study, an irreversible electric field induced AFE-to-FE phase transition is verified at room temperature. Dielectric and in situ temperature dependent X-ray analysis evidence that the phase transition sequence in PLZT 3/90/10-based ceramics can be readily altered by poling. A first order antiferroelectric-paraelectric (AFE-to-PE) transition occurred at ∼190 °C in virgin sample and at ∼180 °C in poled sample. In addition, a FE-to-AFE transition occurs in the poled ceramic at much lower temperatures (∼120 °C) with respect to the Curie range (∼190 °C). The temperature-induced FE-to-AFE transition is diffuse and takes place in a broad temperature range of 72–135 °C. The recovery of AFE is accompanied by an enhancement in the piezoelectric properties.

铅_0.97的La _0.03（锆_0.9的Ti _0.1）_0.9925 Ô ₃（PLZT 3/90/10）通过与反铁电/铁电（FE / AFE）相边界附近的组合物的固态反应制备的陶瓷进行了研究。从极化电场对P（E）的依赖性以及非原位X射线研究，在室温下验证了不可逆电场引起的AFE到FE相变。电介质和原位与温度相关的X射线分析表明，通过极化可以轻松改变基于PLZT 3/90/10的陶瓷中的相变顺序。一阶反铁电-顺电（AFE到PE）转变发生在原始样品的约190°C和极化样品的约180°C。此外，在极性陶瓷中，相对于居里温度范围（〜190°C），在低得多的温度（〜120°C）下会发生FE到AFE的转变。温度引起的FE到AFE的过渡是分散的，发生在72–135°C的较宽温度范围内。AFE的恢复伴随着压电性能的增强。
