Slip casting process under the imposition of a magnetic field is an excellent way for crystal aligned material formation. To investigate the alignment behavior of crystals suspended in a solvent under the imposition of a magnetic field, X-ray was irradiated on the slurry composed of bismuth particles with polydimethlsiloxane under the different intensity of a static magnetic field. Here, bismuth was chosen as a sample material to examine the alignment behavior because it had relatively large anisotropy in magnetic susceptibility among metals and ceramics. The XRD intensity of bismuth (110) plane peak was intensified by imposing the magnetic field. This well agreed with the theoretical prediction. And both the attained time to the saturation of the XRD intensity of the bismuth (110) plane peak and the saturated value were a function of the magnetic field intensity. Therefore, the alignment behavior of the bismuth particles under the imposition of a magnetic field could be detected using this method. The effective magnetic susceptibility difference of the bismuth particles estimated by the time dependence of the XRD intensity of the bismuth (110) plane peak was small compared to that of the single crystal. This suggested that the bismuth particles might aggregate each other.
