Summary

Results of hot pressing using self-propagating synthesis, of refractory ceramics, especially those based on Ti, are reported. Initiation of ignition outside of the graphite dies by means of a powder fuse, as opposed to spontaneous ignition induced by die heating, was emphasized. Achievement of high densities in TiC-based bodies was favored by use of excess Ti metal. However, this did not similarly favor achievement of high densities in bodies containing substantial amounts of high densities in bodies containing substantial amounts of TiB2, product. Results of experiments designed to yield hot-pressed bodies of Al2O3 - TiB2 mixtures are also discussed. Resultant physical properties and microstructures are presented.
