晶粒织构化是利用铁电陶瓷中的本征介电和压电各向异性的已知方法。然而，晶体织构对各向异性非本征贡献（包括畴壁运动）的作用还不清楚。在这里，我们研究的介电和压电性能和小信号介电非线性在K0.5Na0.5NbO3陶瓷在不同方向的纹理标本和比较陶瓷没有晶体纹理。我们表明，在伪立方100磁极具有最大的取向密度的方向表现出增强的纵向压电响应和较低的介电非线性。
Grain texturing is a known method of exploiting the intrinsic dielectric and piezoelectric anisotropy in ferroelectric ceramics. However, the role of crystallographic texture on anisotropic extrinsic contributions including domain wall motion is not yet understood. Here, we investigate the dielectric and piezoelectric properties and small signal dielectric nonlinearities in K0.5Na0.5NbO3 ceramics in different directions of textured specimens and compare to ceramics without crystallographic texture. We demonstrate that directions in which pseudo-cubic 〈100〉 poles have greatest orientation density exhibit both an enhanced longitudinal piezoelectric response and lower dielectric nonlinearity.
