Vapour-phase reaction of AlCl3 and NH3 at 800 to 1000-degrees-C was performed, and AIN produced was made infiltrate an Al2O3 fabric to form AIN matrix-Al2O3 fibre composites. The composites were characterized by observation of the appearances and by analyses with X-ray diffraction and scanning electron microscopy. The matrices of the composites prepared at above 900-degrees-C had lustrous, smooth surfaces and revealed the preferred orientation to c-axis. The composite was constituted by the substrate layer and the surface layer. The fibres in the substrate layer were covered with radially-grown, columnar AIN grains with a maximum height of 15-mu-m. The surface layer was a dense AIN film 50-mu-m thick. Both the layers interlocked each other with mediation of the radially-grown AIN grains covering the fibres. The formation mechanism of the composites was deduced from the morphology. The wettability with a molten dental alloy was very low.
