Strong, high-temperature ceramics are defined as those materials that can withstand thermal cycling without failure which is necessary for their use in high temperature structural applications. For this reason, hot-pressed Si3N4 and SiC are emphasized. The relations between fabrication parameters, microstructure and strength are presented for both materials. Other structural considerations, viz., resistance to thermal shock, impact and oxidation are reviewed. Finally, current directions for obtaining improved and new materials are discussed.
