Texture development in zirconia-dispersed alumina composites by slip casting in a high magnetic field

Many trials have been reported for the production of textured ceramics. Recently, such processing using a high magnetic field has been developed. After the suspension was compacted in a high magnetic field, a green body with a slight degree of crystallographic orientation was obtained. The degree of texture increased with increasing temperature. After densification, grains grew to produce ceramics with a higher degree of crystallographic orientation. We were able to produce a highly textured microstructure. In this paper, we discuss the relationship between the microstructure and the crystalline orientation, and demonstrate that the crystalline orientation depends on the grain size.
