Orientation of titania-alumina systems by slip casting under a high magnetic field

Abstract

The developing texture is one possible way in order to improve the properties of ceramics. Susceptibility is very small in diamagnetic ceramics such as Al₂O₃ and TiO₂; therefore, the effects of high-magnetic field on these ceramics had been generally neglected. Recently, superconducting magnet technologies have developed and have been used for applications to such feeble magnetic materials. We demonstrate that the texture of titania whisker and alumina can be controlled by slip casting of well-dispersed suspensions of the particles in a high magnetic field.
