Preparation and characterization of Ca_{1 −x} La _x Ti_{1 −x} Co _x O₃ (0·00<x⩽0·50) system

Abstract

The possibility of the formation of solid solution in the system Ca_{1 −x} La _x Ti_{1 −x} Co _x O₃ forx⩽0·5 has been investigated. X-ray diffraction studies show that compositions withx=0·05, 0·1, 0·2, 0·3 and 0·5 prepared by the ceramic method are single-phase materials. All the compositions have a structure similar to CaTiO₃ with a pseudo-cubic unit cell. Preliminary studies show that interfacial polarization contributes significantly to their dielectric constant.
