چکیده انگلیسی
[0.9(0.94Na0.5Bi0.5TiO3â0.06BaTiO3)â0.1NaNbO3]-xZnO (NBT-BT-NN-xZnO, x=0, 0.5Â wt%, 1.0Â wt%, 1.5Â wt%, and 2.0Â wt%) ferroelectric ceramics were fabricated using a conventional solid-state reaction method. The effects of ZnO content on dielectric, energy-storage and discharge properties were systematically investigated. Dielectric constant and difference between maximum and remanent polarization were significantly improved by ZnO doping. Dielectric constant of NBT-BT-NN-1.0-wt% ZnO was 3218 at 1Â kHz and room temperature, i.e. one time bigger than that of pure NBT-BT-NN ceramic. As a consequence, a maximum energy-storage density of 1.27Â J/cm3 with a corresponding efficiency of 67% was obtained in NBT-BT-NN-1.0-wt% ZnO ceramic. Moreover, its pulsed discharge energy density was 1.17Â J/cm3, and 90% of which could be released in less than 300Â ns. Therefore, ZnO doped NBT-BT-NN ceramic with a large energy-storage density and short release time could be a potential candidate for applications in high energy-storage capacitors.
