“…The comparison of d 33 versus T C values for other high Curie temperature ceramics reported previously is shown in Figure 8 6,7,23‐36,53‐59 . In terms of BF‐PT‐based piezoelectric ceramics, high d 33 was recently achieved by the addition of ABO 3 compound or substitutional doping with the rare‐earth elements.…”

“…In other words, the enhancement of piezoelectric performance is achieved in detriment of a high structural distortion (high T C ). Even so, a novel BF‐PT‐based ternary system was designed with a high piezoelectric coefficient while retaining high Curie temperature, compared to other reported systems 23‐36 …”

“…The other reason is that high leakage current and dielectric loss make it difficult to be proper electrical poled for ceramics. Thus, there is a growing number of reports devoted to d 33 enhancement by site engineering 23‐36 . However, the general principles for its rational use have not yet been well achieved.…”

The requirement for ferroelectric ceramics with a high Curie temperature and a high piezoelectric coefficient remains an important research task for high‐temperature sensors and actuators applications. (0.76‐x)BiFeO3‐0.24PbTiO3‐xBa(Sn0.2Ti0.8)O3 (BF‐PT‐BST) piezoelectric ceramics were fabricated using the solid‐state reaction method. XRD analysis indicated that the incorporation of large ionic radius Ba2+ at A‐site and nonferroelectric‐active Sn4+ at B‐site generated a decrease in the tetragonality degree c/a. A wide multiphase coexistence region was formed with the content of BST ranging from 0.13 to 0.28. The enhanced piezoelectric coefficient (d33 ~ 200pC/N) was achieved while maintaining a high Curie temperature (TC ~ 500°C) and a high depolarization temperature (Td ~ 450°C) for the composition of 0.6BF‐24PT‐0.16BST. TEM patterns provided clear evidence for the presence of nanodomains (~2nm) would be the predominant source for the enhanced piezoelectricity for the composition x = 0.20. The designed BF‐PT‐BST ternary system provides great potential for high‐temperature piezoelectric applications.
