<p>Infiltration reaction products are provided of molten silicon and certain blends of particulated carbon and various particulated inorganic materials substantially unreactive to molten silicon, such as boron nitride particles. These molten silicon infiltration products of reaction are readily machinable and can be applied, or formed in-situ as contiguous layers on silicon carbide, or silicon-silicon carbide substrates, etc., to produce multilayer composites having an improved impact strength over the base refractory structure.</p> |
