Dielectric properties of the system Ca1−xYxTi1−xCoxO3(0.00 x 0.15)

The dielectric behaviour of the compositions withx?0.15 in the system Ca_1-xY_xTi_1-xCo_xO₃ 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.
