调整压电陶瓷的晶体取向对改善其性能非常有用。陶瓷中的取向可以通过模板化的晶粒生长、热锻造等来控制。我们的重点是使用强磁场来实现即使在抗磁性陶瓷中的晶体取向。在以往的研究中，虽然这些方法只能控制一个方向的取向，但很难控制陶瓷中的多轴取向。在这项研究中，我们证明了在Bi4Ti3O12压电陶瓷中，c轴和c轴的排列是由强磁场和片状颗粒共同控制的。我们还用电子背散射衍射分析估算了其取向度。当磁场作用于片状颗粒时，80%的颗粒与c轴的倾角成正比，垂直方向小于10°，73%的颗粒与c轴的夹角小于10°。
Tailoring the crystallographic orientation in piezoelectric ceramics is very useful for improving their properties. Orientation in ceramics can be controlled by templated grain growth, hot forging, etc. We have focused on using a strong magnetic field for the crystallographic orientation even in diamagnetic ceramics. In a previous study, although only a one-directional orientation could be controlled by these methods, it was difficult to control the multi-axis orientation in the ceramics. In this study, we demonstrated that alignments of the c-axis and the axis in Bi4Ti3O12 piezoelectric ceramics were controlled by using a strong magnetic field as well as platelet particles. We also estimated the degree of orientation by an electron back scattering diffraction analysis. When the magnetic field was applied to the platelet particles, appropriately 80% of the grains were aligned with the tilt angle made by the c-axis and the vertical direction less than 10° and 73% of grains were oriented with the angle between the axis and the magnetic field less than 10°.
