| 摘 要： | 采用传统固相法制备了CeO2掺杂0.9Bi4Ti3O12–0.1K0.5Na0.5NbO3(BTO-KNN) 铋层状陶瓷材料。系统研究了CeO2掺杂对BTO-KNN基陶瓷物相结构、微观结构以及电性能的影响. 结果表明：所有陶瓷样品均为单一的铋层状结构；BTO-KNN基陶瓷的压电性能随着CeO2的掺杂而显著提高，损耗明显降低。当CeO2掺量为0.75 wt% 时，样品具有最佳的电性能: d33=28 pC/N，介电损耗tan δ=0.29%，机械品质因数Qm = 2897，剩余极化强度Pr = 11.83 μC/cm2，且居里温度 Tc 高达615 ℃；研究结果表明CeO2掺杂0.9Bi4Ti3O12–0.1K0.5Na0.5NbO3铋层状陶瓷是种潜在的高温陶瓷材料。
