In this study, NBN ceramics were processed through solid-state sintering route, resulting in single perovskite phase crystallization and dense microstructure with high dielectric constant and low dielectric loss. These ceramics demonstrated recoverable energy density and ultra-high efficiency at room temperature, making them suitable candidates for power pulsed applications.
Ceramics-based capacitors with excellent energy storage characteristics, fast charging/discharge rate, and high efficiency have received significant attention. In this work, Na0.73Bi0.09NbO3(NBN) ceramics were processed through solid-state sintering route. The investigated ceramics were crystallized in a single perovskite phase. Dense microstructure, with small average grain size (similar to 0.92 mu m) is obtained for the investigated ceramics. A high dielectric constant >1000 accompanied by a low dielectric loss was achieved for these ceramics at ambient temperature. A recoverable energy density similar to 0.92 J/cm(3)and ultra-high efficiency of 96.33% at 138 kV/cm were obtained at room temperature. Furthermore, a lower discharging time of 0.14 mu s was also achieved. This material is a suitable candidate for power pulsed applications.
