BF-based ceramic materials are considered as potential lead-free energy storage materials due to their theoretical high saturation polarization intensity and high Curie temperature [25, 26]. However, the volatilization temperature of Bi 2 O 3 is low (∼825 °C), and the actual sintering temperature is often much higher than this temperature.
