We have designed and fabricated a compact, 250 cm3 electric field cooling alternate current poling (FC ACP) system and obtained an enhanced dielectric permittivity (e T 33/e 0) of 7920 which was 10 to 33% larger than that of high temperature (HT) ACP of 0.70Pb(Mg1/3Nb2/3)O3-0.30PbTiO3 (PMNT) single crystal (SC) with phase change temperature (T pc) of 93 °C. However, when the FC ACP temperature from 200 to 35 °C was applied for 0.31Pb(In1/2Nb1/2)O3-0.43Pb(Mg1/3Nb2/3)O3-0.26PbTiO3 (PIMNT) SC with a T pc of 136 °C, the e T 33/e 0 decreased by 55% compared with that of HT ACP. Temperature dependence of the e T 33/e 0 and phase analysis by X-ray diffraction of these SCs produced by a continuous-feeding Bridgman process showed clear different properties. We conclude the effects of FC ACP on the electrical and physical properties are different from the compositions, T pc, Curie temperature, etc., and it is required to find the best FC ACP condition according to each SC.

场冷交流极化对连续供料布里奇曼法制备的Pb(Mg1/3Nb2/3)O3-PbTiO3基单晶电学和物理性能的影响

我们设计并制造了一个紧凑的 250 cm3 电场冷却交流极化 (FC ACP) 系统，并获得了 7920 的增强介电常数 (e T 33/e 0)，比高温 ( HT) 0.70Pb(Mg1/3Nb2/3)O3-0.30PbTiO3 (PMNT) 单晶 (SC) 的 ACP，相变温度 (T pc) 为 93 °C。然而，当 FC ACP 温度从 200 到 35 °C 时，对于 0.31Pb(In1/2Nb1/2)O3-0.43Pb(Mg1/3Nb2/3)O3-0.26PbTiO3 (PIMNT) SC，T pc 为 136 °C，与HT ACP 相比，e T 33/e 0 降低了55%。e T 33/e 0 的温度依赖性和通过连续进料布里奇曼工艺生产的这些 SC 的 X 射线衍射的相分析显示出明显不同的特性。
