AbstractWhen Bi4Ti3O12is viewed as a piezoelectric material, since the direction of the spontaneous polarization is limited in two dimensions, it is necessary to perform grain orientation. In this paper, as a method for the grain orientation at room temperature, a cold‐uniaxial pressing method is considered, and the fabrication method of Bi4Ti3O12grain‐orientation ceramic is examined. Furthermore, the electrical characteristics of the obtained grain‐orientation sample are also examined. This method performs grain orientation by utilizing the shape anisotropy of the ceramic powder. Therefore, first, the relation between the firing process and the grain growth is examined for normal firing sample. Next, the orientation sample is obtained by applying a uniaxial pressing and a main firing to the obtained plate‐like primary particles. As a result, it has been found that the orientation by this cold‐uniaxial pressing method is due both to the orientation of primary particles during the deformation by uniaxial pressing, and also to the grain growth during the main firing. It has also been found that oriented samples comparable to the hot‐working method can be obtained by this method in terms of grain orientation and electrical char
