Abstract
We achieved to produce the highly textured microstructure of undoped dense alumina prepared by slip casting in a high magnetic field and subsequent heating. Well-dispersed alumina aqueous suspensions were prepared by adding appropriate amount of polyelectrolyte. Alter the suspension was consolidated by slip casting in high magnetic field, the green body with slight degrees of crystallographic orientation was obtained. The degree of texture increased with increasing temperature. After densification, alumina grains grow to yield ceramics with textured grains and high degrees of crystallographic orientation. This processing can be applied to other ceramics with asymmetric unit cell.
