英文摘要	The pulsed power supply that generates megawatts of electrical power has drawn important attention for many decades. Despite that the large energy output has been obtained in lead-containing materials such as Pb(Zr0.95Ti0.05)O-3 (PZT95/5) ceramics, lead-free ferroelectric candidates are highly desired due to the environmental concerns. In this work, we report the depolarization behavior of lead-free ternary 0.99[0.98(Bi0.5Na0.5)(Ti0.995Mn0.005)O-3-0.02BiAlO(3)]-0.01NaNbO(3) ferroelectric ceramics under shock wave compression. A current profile with a maximum value of similar to 25 A and a FWHM of similar to 2.3 mu s was obtained. Particularly, the poled BNT-BA-0.01 NN ceramics were almost completely depolarized under high strain rate loading, releasing a high charge density J of 38 mu C/cm(2). The released J was approximately 96% of thermal-induced charge density (similar to 40 mu C/cm(2)), which was 18% higher than that of PZT95/5 ceramics. The shock induced depolarization mechanism can be attributed to the ferroelectric-ergodic relaxor phase transition. These results reveal the BNT-based ceramics as promising candidates for pulsed power applications. Published by AIP Publishing.
