Abstract:

采用固相法制备了Ce和Sr复合掺杂的Bi4Ti2.92Nb0.08O12.04(BTN＋0.5x%CeO2＋0.5x%SrCO3，0≤x≤1.5，质量分数)铋层状高温无铅压电陶瓷，研究了不同含量的Ce和Sr掺杂对BTN系陶瓷微观结构及电性能的影响。结果表明样品均为单一的铋层状结构相，Ce和Sr的引入明显提高了陶瓷的压电性能。当掺杂量x＝0.9时，样品具有最佳性能压电常数d33＝29pC/N，平面机电耦合系数kp＝8.77%，介电损耗tanδ＝0.13%，剩余极化强度Pr＝15.87μC？cm－2和Curie温度TC＝627℃。此外，该组分陶瓷样品具有良好的压电稳定性，表明该材料在高温领域下具有良好的应用前景。
