Core-shell structure and domain engineering in Bi0.5Na0.5TiO3-based ceramics with enhanced dielectric and energy storage performance

Journal of Materiomics, 2023
Core–shell structured Bi0.5Na0.5TiO3KTaO3 + x% (in mass) Li2CO3 ceramics were fabricated in this study. Increasing x from 0 to 2 leads to the decrease of sintering temperature from 1 175 °C to 1 020 °C.
