Effect of processing route on the dielectric behavior of (Sr0.50Ca0.15La0.35)(Ti0.65Co0.35)O3 ceramic

Abstract

Dielectric properties of valence compensated perovskite oxide Sr0.50Ca0.15La0.35Ti0.65Co0.35O3 prepared by a conventional solid state reaction and by a novel semi-wet route have been studied. A peak is observed in ∈r vs T plots of both the samples whose position depends on frequency. The behaviour resembles that of relaxor ferroelectric in both the cases. However, the temperature of peak maxima depends on the processing route.
