Dielectric relaxator behaviour of Sr0.8La0.2Ti0.8Co0.2O3

Abstract

Sr1xLaxTi!. xCoxO3for x 0.4 exhibits dielectric relaxator behaviour. The effect of firing temperature and different electroding on the dielectric properties of the sample Sr0.8La0.2Ti0.8Co0.2O3has been investigated. Higher firing temperatures have no effect on the microstructure and on the resulting dielectric properties. On electroding with silver paint containing a low melting glass, CuO and Bi2O3and heat-treating at 900 K for 15 minutes, the dielectric constant increased and the dielectric loss decreased. The dielectric characteristics have been analysed using complex plane impedance analysis. © 1990, Taylor & Francis Group, LLC. All rights reserved.
