Abstract:
In this study, (1– x )Bi 0.5 Na 0.5 TiO 3 – x BiScO 3 (BNT– x BS) ceramics were synthesized via conventional solidstate reaction sintering. The effects of the BiScO 3 content on the surface microstructure,
energy storage, strain, and dielectric properties of BNT– x BS ceramics were systemically investigated. Results indicated that the phase structure of BNT– x BS ceramics transformed from the rhombohedral phase into the pseudo-cubic phase. As the increasing BiScO 3 content, the average grain size decreased. BiScO 3 destroyed the long-range ordered ferroelectric phase, enhancing relaxor behavior. Energy storage density initially increased and then decreased, reaching a maximum of 0.17 J/cm 3 at x = 0.1. In addition, the maximum
energy storage efficiency was 59% at x = 0.2. The BiScO 3 content significantly affected the electrical properties of BNT– x BS ceramics.
