In this paper, regarding colloidal shaping in a rotating magnetic field, the fabrication and evaluation were described for various crystal-oriented ceramics including c-axis oriented ZnO, piezoelectric ceramics with tungsten bronze crystals as Sr2KNb5O15, (Sr,Ca)2NaNb5O15 (SCNN) and (Sr,Ba)Nb2O6. In order to shorten the shaping time, which is the problem of this method, a shaping method was proposed in which a slurry was prepared with a solution containing an ultraviolet (UV) curing monomer, and the slurry was solidified by UV irradiation after orientation treatment in a magnetic field. Crystal-oriented SCNN and Ca10(PO4)6(OH)2 compacts were prepared by holding for several tens of seconds. The experimental results were examined based on the theory regarding the UV curing depth and rotation time, and it was confirmed that the experimental results follow the theory. In addition, regarding the fabrication of laminated ceramics by the stereolithography method, c-axis oriented SCNN ceramics with a thickness of 600 μm were produced, and the piezoelectric property were also confirmed. In the future, particle orientation in a low magnetic field were achieved, which would be thought to enhance versatility.
