研究了K含量对LiCe共取代（Na 1 −xKx）0.5Bi4.5Ti4O15基陶瓷性能的影响。居里温度（TC）随着K含量的增加从641 °C逐渐降低到551 °C。本文还研究了压电陶瓷的压电系数d33、厚度耦合系数kt和机械品质因数Q。（Na0.5Bi0.5）0.80（Li0.5Ce0.5）0.10[]0.10Bi4Ti4O15（x = 0.00）陶瓷的电阻率分别为28 pC/N、25%和2693，同时具有高的TC（~ 641 °C）和稳定的压电性能，这表明（LiCe）改性的Na0.5Bi4.5 Ti4 O 15基材料是高温应用的有希望的候选材料。
The effect of K content on the properties of LiCe co‐substituted (Na1−xKx)0.5Bi4.5Ti4O15‐based ceramics was investigated. The Curie temperature (TC) gradually decreases from 641 to 551 °C with increasing the K content. The piezoelectric coefficient d33, thickness coupling factor kt, and mechanical quality factor Q of (Na0.5Bi0.5)0.80(Li0.5Ce0.5)0.10[]0.10Bi4Ti4O15 (x = 0.00) ceramic were found to be 28 pC/N, 25%, and 2693, respectively, together with the high TC (∼641 °C) and stable piezoelectric properties, demonstrating that the (LiCe) modified Na0.5Bi4.5 Ti4O15‐based material a promising candidate for high temperature applications.
