Tetramethoxysilane and phenol-formaldehyde condensate in the liquid state were polymerized with water. The polymer was carbonized and heated at 1750°-1850°C. A mixture of fine β-SiC and C powders was obtained. Hot pressing of using B as a sintering aid yielded a SiC-C composite. The composite had higher fracture toughness than sintered monolithic SiC. The crack bridging mechanism by the C particles increased the fracture toughness of the SiC-C composite.
