In this investigation, based ceramic composites were fabricated by in-situ reaction hot pressing using , TiC SiC powder as starting materials. The reaction synthesized composites by hot pressing at was found to posses very high relative density. The reaction synthesized composites comprise , , SiC and graphite by the reaction between TiC and . The newly formed and graphite was embedded both inside grain and at grain boundary . The mechanical properties of reaction synthesized -graphite composites were more enhanced compared to those of monolithic .
