Article Preview

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 and 1300. 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.
