Patent ID: 7723248

Claim:
A method of manufacturing a ceramic composite, the composite characterized in comprising a phase having as its principal component, at a content of 40 to 98 wt. %, a pure carbon allotrope of 30 nm or less average phase size, said carbon being one selected from graphite, amorphous carbon, carbon black, and fullerenes, and the composite characterized in comprising a ceramic phase having an average grain size of 30 nm or less and constituted by a ceramic matrix that excludes pure carbon; the method characterized in that a powder blend, having an average particle size of 30 nm or less, of a ceramic powder and of a carbon powder is molded, and the obtained molded form is sintered within a non-oxidizing atmosphere at a sintering temperature of 800 to 150000 and a sintering pressure of 1000 MPa or more.
