Abstract

The effect of (Li,Ce) substitution at the A-site on the properties of Na_0.25K_0.25Bi_4.5Ti₄O₁₅ (NKBT)-based ceramics was investigated. The piezoelectric coefficient d₃₃ of the [(Na_0.5K_0.5)Bi]_0.42(LiCe)_0.04[]_0.04Bi₄Ti₄O₁₅ ceramic was found to be 25 pC N^-1, the highest value of the NKBT-based ceramics, and almost twice the d₃₃ values of pure NKBT ceramics (∼13 pC N^-1). The thickness coupling factor k_t was found to be 20%, which, together with the high T_C (∼615 °C) and stable piezoelectric properties, suggests that (Li,Ce)-modified NKBT-based materials are promising candidates for high-temperature applications.
