Abstract
A process for producing a sintered silicon carbide composite includes the steps of forming a first dispersion of diamond crystals and carbon black in paraffin, as well as forming a second dispersion of carbon fiber, carbon black and filler in paraffin. The two dispersions are compacted together to form an integral bi-layer composite which is then subjected to a vacuum for a period of time at a temperature sufficient to vaporize essentially all of the paraffin. Silicon is heated to cause liquification and direct infiltration into both layers of the composite after which the composite is sintered under conditions sufficient to produce a .beta.-silicon carbide binder uniting the composite.
