Abstract
The effect of K content on the properties of LiCe co-substituted (Na 1-xK x) 0.5Bi 4.5 5Ti 4O 15-based ceramics was investigated. The Curie temperature (TC) 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 0.5Bi 0.5) 0.80(Li 0.5Ce 0.5) 0.10[] 0.10Bi 4Ti 4O 15 (x 0.00) ceramic were found to be 28pC/N, 25%, and 2693, respectively, together with the high TC (∼641 °C) and stable piezoelectric properties, demonstrating that the (LiCe) modified Na 0.5Bi 4.5 Ti 4O 15-based material a promising candidate for high temperture applications.
