A procedure for processing SiC-whisker-reinforced Al/sub 2/O/sub 3/ has been developed which enables composites with good strength and creep properties to be fabricated. The procedure involves mixing components as dispersed slurries, press filtration of the slurries to produce green bodies, and hot pressing the green bodies in close fitting graphite dies. The resulting composites exhibit homogeneous microstructures and have high strength, high toughness, and high creep ductility.
