Abstract

The dielectric behaviour of the compositions withx⩽0.15 in the system Ca1−x Y x Ti1−x Co x O3 sintered and cooled in air has been studied. Space-charge polarization which arises due to the presence of chemical inhomogeneities at the micro-level contributes significantly to their dielectric constant. The composition with x=0.05 exhibits temperature and frequency-independent dielectric constant and very small dielectric loss.
