| 英文摘要 | Lead-free 0.9BaTiO(3)-0.1(Bi0.9Na0.1)(In0.8Zr0.2)O-3 (0.9BT-0.1BNIZ) ferroelectric relaxor ceramic was synthesized by solid-state reaction method. A dense microstructure and fine grain size was obtained with addition of BNIZ content. The dielectric behaviors indicated the dominance of ergodic relaxor phase. The 0.9BT-0.1BNIZ ceramic was found to possess an enhanced recoverable energy density (W-R similar to 1.33 J/cm(3)) and efficiency (eta similar to 88%) under 18 kV/mm at room temperature. What's more, WR is maintained >= 0.53 J/cm(3) with 94% under 10 kV/mm and the variation of W-R is less than 15% over 25 similar to 140 degrees C. The high stability of energy storage properties is mainly ascribed to the characteristics of ergodic relaxor phase. The stored energy was released in sub-microseconds (similar to 0.19 mu s). The superior current density (CD similar to 796 A/cm(2)) and the power density (P-D similar to 39.8 MW/cm(3)) were obtained simultaneously. The enhanced W-R and the superior charge-discharge performances strongly demonstrate that the BT-based ceramics are promising candidates of high -power pulse capacitor applications. |
