Abstract
The ceramic system PbZr0.6Ti0.4O3 was prepared by a solid state method and impedance measurements were carried out as a function of frequency (100 Hz-10MHz) in the temperature range 370 K-869 K. Equivalent circuit models that represent the data below and above the transition temperature were arrived at by comparing the experimental plots with the computersimulated behavior obtained for model circuits. Below the transition temperature the equivalent circuit model comprises a series LCR combination connected in series with a parallel RC network where as for higher temperatures it contains three parallel RC circuits connected in series. Variation of the values of the components as a function of temperature was also studied.

Keywords: PZT, Impedance, immittance, modeling, ceramic, equivalent circuit.
