Enhanced piezoelectric properties of SrBi4Ti4O15–(Na0.5 Bi0.5)Bi4Ti4O15 ceramics with cerium modification

The composition of Sr0.9 (Na0.5 Bi0.5)0.1–Bi4Ti4O15 (SNBT) with excellent piezoelectric properties had been found recently. And basis on that, the effect of cerium modification SNBT-based ceramics was investigated in this paper. The Curie temperature and piezoelectric constant (d33) for the 0.50 wt% cerium-modified SNBT-based ceramics were found to be 598 °C and 27pC/N, respectively, which, together with the stable aging performance and thermal annealing properties, demonstrated that the cerium-modified SNBT-based materials are promising candidates for high-temperature applications.
