“…Figure g shows a gradual decrease in the a / b value with increasing (LiCeNd) doping, indicating a gradual enhancement of the pseudotetragonality . Thus, the samples neighboring x = 0.12 exhibit behaviors reminiscent of a polymorphic phase boundary (PPB) between the orthorhombic phase and the tetragonal phase, which is beneficial to improve piezoelectric properties …”

High-temperature piezoelectric materials, which enable the accurate and reliable sensing of physical parameters to guarantee the functional operation of various systems under harsh conditions, are highly demanded. To this end, both large piezoelectricity and high Curie temperature are pivotal figures of merit (FOMs) for high-temperature piezoceramics. Unfortunately, despite intensive pursuits, it remains a formidable challenge to unravel the inverse correlation between these FOMs. Herein, a conceptual material paradigm of multiscale structural engineering was proposed to address this dilemma. The synergistic effects of phase structure reminiscent of a polymorphic phase boundary and refined domain morphology simultaneously contribute to a large piezoelectric coefficient d 33 of 30.3 pC/N and a high Curie temperature T C of 740 °C in (LiCeNd) codoped Na 0.5 Bi 2.5 Nb 2 O 9 (NBN-LCN) ceramics. More encouragingly, the system has exceptional thermal stability and is nonsusceptible to mechanical loading. This study not only demonstrates that the high-performance and robust NBN-LCN high-temperature piezoceramics hold great potential for implements under harsh conditions but also opens an avenue for integrating antagonistic properties for the enhancement of the collective performance in functional materials.
