文摘

BNKT-xCo ceramics were prepared by solid-state reaction method. Electrical properties of BNKT ceramics are changed by the doping of BiCoO3. The doping causes a decrease in lattice parameters and an increase in grain size. Td of the ceramics increases with increasing x. Oxygen vacancies play key role in determining electrical properties of the ceramics.
