Abstract

BiScO3-BaTiO3 with (K1/2Bi1/2)TiO3 [BSBT-KBTx] in the perovskite solid solution system were prepared by conventional ceramic processing for potential high temperature capacitors. The effect of KBT on the dielectric properties of BSBT was investigated as a function of temperature and frequency. The BSBT-KBT20 exhibited high dielectric permittivity and low dielectric loss over the temperature range from 100°C to 300°C with flat coefficients of temperature (TCe{open}s). In addition, BSBT-KBTx were observed to possess dielectric relaxation behavior at temperatures (> RT) as observed in lead-based relaxors. Furthermore, the E-field polarization behavior was investigated showing high energy density of 1.28 J/cm3 at 100 kV/cm for the BSBT-KBT20.
