中文摘要：

分析了（K0.5Na0.5）NbO3（简写为KNN）基陶瓷压电性能温度稳定性差的原因,结合KNN固溶体的相图,提出了解决KNN基陶瓷压电性能温度稳定性差的新方法.为了验证此方法的可行性,设计了0.9（K1-xNax）NbO3-0.06LiNbO3-0.04CaTiO3（简记为KNLN？CaTiO3）陶瓷.系统研究了KNLN－CaTiO3陶瓷的结构和性能.实验结果表明：KNLN-CT（x=0.54）陶瓷在宽阔的温度范围（25－320℃）内表现出良好的温度稳定性,在x=0.54处获得了相对较高的压电性能（d33=152pC/N）.这个结果证实了我们提出的解决KNN基陶瓷压电性能温度稳定性差的方法是可行的,具有使用价值.
