The effect of K content on the properties of LiCe co‐substituted (Na 1− x K x ) 0.5 Bi 4.5 Ti 4 O 15 ‐based ceramics was investigated. The Curie temperature ( T C ) gradually decreases from 641 to 551 °C with increasing the K content. The piezoelectric coefficient d 33 , thickness coupling factor k t , and mechanical quality factor Q of (Na 0.5 Bi 0.5 ) 0.80 (Li 0.5 Ce 0.5 ) 0.10 [] 0.10 Bi 4 Ti 4 O 15 ( x = 0.00) ceramic were found to be 28 pC/N, 25%, and 2693, respectively, together with the high T C (∼641 °C) and stable piezoelectric properties, demonstrating that the (LiCe) modified Na 0.5 Bi 4.5 Ti 4 O 15 ‐based material a promising candidate for high temperature applications.
