Abstract
0.475BNT-0.525BCTZ-xwt%MgO ceramics were densified by microwave sintering method and their phase compositions and dielectric properties were investigated. The XRD results reveal that all samples possess a perovskite structure and the secondary phase of MgO can be observed in the MgO-doped samples. The maximum polarization of the MgO-doped samples sintered by microwave sintering are higher than that of the samples sintered by traditional sintering, thus a higher energy storage density can be achieved. The dielectric breakdown strength of the samples are greatly improved with the increasing content of MgO. The x=5 sample exhibits a high dielectric breakdown strength of 17.91Â kV/mm and a high energy storage density of 1.37Â J/cm3.
