In an attempt to strengthen and toughen silicon carbide ceramics, fully dense SiC-A1N alloys containing up to 25mol%A1N were fabricated by hot-isostatic pressing of the reaction-synthesized SiC-A1N solid solution powders. It was found that the solution of A1N yields much higher strength (up to 1000MPa at 5mol%KA1N), and increases fracture toughness of SiC. In the SiC-A1N composites prepared by hot-isostatic pressing of the SiC and A1N elemental powder mixtures, the addition of A1N particales improves fracture toughness more effectively in comparison with the single phase alloys.
