We have demonstrated that textured Al2O3-mullite-SiC nanocomposites can be fabricated by slip casting followed by partial oxidation - reaction sintering of mixed suspensions of Al2O3 and SiC powders in a high magnetic field. The sintered density was changed by the degree of oxidation at 1200°C and 1300°C. The degree of orientation of alumina in the nanocomposite was examined on the basis of the X-ray diffraction patterns and scanning electron micrographs. It is confirmed that alumina-oriented nanocomposites were fabricated. The three-point bending strength at room temperature was observed for the nanocomposites.
