摘要: A detailed study of the polarization and depolarization behavior 7:65:35 8:65:35 lead lathanum zirconate titanate transparent ceramics under dc bias constant heating rates has been carried out. The dielectricpermittivity exhibits a new anomaly near 0 °C in freshly thermally depoled samples which is associated with buildup macrodomains development remanent polarization. From continuity dispersive behaviors it suggested that dielectric change at so‐called α–β transition T d not conventional phase change, but rather loss macro‐ordering decay back to disordered microdomain texture.
