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

The dielectric behaviour of the compositions with x less than 0.15 in the system Ca1-xYxTi1-xCoxO3 sintered and cooled in air was studied. Space-charge polarisation which arises due to the presence of chemical inhomogeneities at the micro-level contributes significantly to their dielectric constant....

Zusammenfassung:	The dielectric behaviour of the compositions with x less than 0.15 in the system Ca1-xYxTi1-xCoxO3 sintered and cooled in air was studied. Space-charge polarisation 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. 11 refs.
