采用固相法制备了Na0.5Bi85Ti7O27+xmol％ MnCO3(NBTO-Mn-x,x=0.00,3.00,5.00,7.00)铋层状压电陶瓷材料,系统研究了MnCO3的引入对Na0.5Bi8Ti7O27共生结构铋层状陶瓷物相结构、微观结构以及电性能的影响.结果表明:所有样品均为单一的共生结构铋层状陶瓷材料,Mn的引入没有改变其物相结构;适量的Mn掺入能明显降低Na0.5Bi8.5Ti7O27陶瓷的介电损耗tanδ,改善其电性能,当x=5.00时,其综合性能最佳:p、d33、Qm、kp和k1分别为p=6.90 g/cm3、d33=19 pC/N、Qm=3230、kp=11.00％、k11=13.40％,该组分陶瓷样品具有良好的热稳定性.
