Title: Temperature dependent impedance and dielectric properties of 0.7 CaTiO₃-0.3 NdAlO₃ ceramics

Abstract: In this paper, dielectric and impedance spectroscopic studies carried out on a 0.7CaTiO₃- 0.3NdAlO₃ composition have been reported. The material is synthesized by the conventional ceramic method and the dielectric measurements are carried out as a function of frequency (1 kHz-4.5 MHz) in the temperature range of 150-303 K. The impedance measurement is carried out at different temperatures to separate the grain and grain boundary contributions. The grain boundary resistance is evaluated from the measured Z-Z” plots. Both of them are found to be decreasing with the increase in temperature.
