N2 - Titania is a very important material for various applications and its properties are expected to be improved by controlling the crystallographic orientation. In this study, we demonstrated that the c-axes of both rutile and anatase were aligned parallel to a magnetic field and we investigated the effect of the orientation on the microstructure development and the effect of the transformation from anatase to rutile on the orientation during heating. When using rutile as the starting material, the c-axis was aligned and the elongated grains were aligned after sintering. When using anatase as the starting material, the c-axis of anatase was aligned parallel to the magnetic field. However, after transformation, the rutile had a tilt and the anisotropic grain growth was suppressed.
