Effect of sintering conditions on microstructure orientation in α-SiC prepared by slip casting in a strong magnetic field

In general, the mechanical and physical properties of a crystal depend on the direction of the crystal axis. The controlled development of the crystallographic texture in ceramics is very useful for improvement of their properties. The preparation of the textured SiC polycrystal was achieved by slip casting in a strong magnetic field. The effects of the sintering conditions and sintering additives on the degree of orientation in the SiC were investigated. The pressing during the liquid phase sintering prevented the development of a texture in the SiC prepared by slip casting in a strong magnetic field.
