Magnetic field processing is an emerging area in ceramic processing which can lead to the development of novel microstructures and the reduction in thermal energy required to obtain dense materials. Some of the current research is focused on increasing the responsiveness of ceramic materials to a magnetic field, which can improve crystallographic texture by altering the magnetic susceptibility anisotropy of the crystallite. In this study, the anisotropy is addressed by incorporating ferromagnetic dopants (soluble in the lattice) and additives (insoluble in the lattice) into diamagnetic ceramics. Magnetic fields are then used to process these materials at room temperature to obtain crystallographic texture during slip casting. Several transition metal and rare earth metal dopants will be compared by calculating the amount of crystallographic alignment from x-ray diffraction measurements. Finally, texture will be retained upon sintering of these materials under ambient atmospheres.
