Grain Engineering Modification of Temperature-Insensitive High Piezoelectricity in Bi0.5Na0.5TiO3-Based Ceramics at Morphotropic Phase Boundary.
The practical application of lead-free Bi0.5Na0.5TiO3 (BNT)-based piezoelectric ceramics is limited by the persistent trade-off between piezoelectric coefficient (d33) and thermal stability, which conventional compositional strategies fail to resolve. Here, we propose a grain engineering approach to decouple this prope...
