Abstract
- A novel synergistic strategy was used to improve the piezoelectric characteristics of high-temperature piezoelectric ceramics. This work combined three commonly used strategies, constructing the Morphotropic Phase Boundary to reduce energy barriers, changing domain structures impacting macroscopic piezoelectric properties, and adjusting BO 6 octahedral distortions reflecting microstructural changes, thus effectively regulating the piezoelectric behaviors of BiFeO 3 -based ceramics. As a result, the 0.67BiFeO 3 -0.32BaTiO 3 -0.01BiAlO 3 component, exhibiting the maximum distortion of the BO 6 octahedron and the coexistence of macrodomains and nanodomains, achieved the optimal piezoelectric characteristics (d 33 = 225 ± 10 pC N−1, T C = 450 °C). Additionally, the ceramic maintained its high piezoelectric properties even at temperatures as high as 280 °C (346 pC N−1). This study presents a novel collaborative design strategy that combines phase structure, domain structure, and BO 6 octahedral distortion, significantly enhancing the development potential of lead-free high-temperature piezoelectric materials in the future.
