A process whereby full density, monolithic ceramic materials are fabricated is described. Elemental powders which are to make up the ceramic compound are reacted by a combustion synthesis process called Self-Propagation High Temperature Synthesis (SHS). When such a reaction takes place in a properly insulated container, a hot, porous ceramic material is produced that is then compacted to high density by a pressure wave produced by a high explosive. This technique has been used to produce high-purity TiC and TiB/sub 2/ at greater than 98% of theoretical density. The size of the plates that can be produced by this method is readily scalable to the 15 cm range or greater in the lateral dimension, and the cost of the ceramics so produced is expected to be lower than with current commercial processes.
