The effect of cationic ratio on the semiconducting and the dielectrical properties of barium metatitanate
The electrical conductivity (670–1070 K), the dielectric constant and the loss factor (240–430 K, 1 kHz) were examined for polycrystalline BaTiO3 (0.99 > Ba/Ti < 1.01) obtained by solid state synthesis at 1720 K under pO2 = 210 kPa. Changes in electrical properties with deviation from stoichiometry, in both cation sublattices, are consistent with the formation of acceptor centres such as VBa and VTi.
