研究了温度对钙钛矿型Pb（Zr0.52Ti0.48）O3陶瓷材料介电、阻抗和直流电导率的影响。通过X射线衍射、热重分析和差热分析对材料的结构、相组成和热性能进行了表征。使用复阻抗谱研究陶瓷的电性能作为温度（从25 ° C至500 ° C）和频率（从100 Hz至1 MHz）的函数。从Arrhenius曲线的斜率计算样品的活化能为0.210 eV（直流电导率与绝对温度的倒数）。在室温下测得铁电环的剩余极化强度（Pr）为1.59 μ C/cm 2，矫顽电场（Ec）为9.35 kV/cm。
The effect of temperature on perovskite Pb(Zr0.52Ti0.48)O3ceramic material on their dielectric, impedance and dc conductivity properties were studied. Structural, phase formation and thermal properties were confirmed by X-ray diffraction, thermogravimetry and differential thermal analysis. The electrical properties of the ceramics were investigated as a function of both temperature (from 25 to 500 °C) and frequency (from 100 Hz to 1 MHz) using complex impedance spectroscopy. The activation energy of the sample was calculated from the slope of the Arrhenius plot as 0.210 eV (dc conductivity vs. inverse of absolute temperature). From the ferroelectric loop measured at room temperature, the remnant polarization (Pr) and coercive electric fields (Ec) are observed as 1.59 μC/cm2and 9.35 kV/cm, respectively.
