Abstract
A SiC whisker-reinforced ceramic composite is prepared by adding about 0.4 to 1.0% by weight of a nonionic polymer, polyvinylalcohol (PVA) to a heat-treated SiC whisker to obtain a SiC whisker slurry, mixing the SiC whisker slurry with a matrix slurry formed at about pH 4 followed by freeze-drying the resulting slurry mixture to produce granules having a uniform packing structure and hot pressing the granules.
