Claims
- 1. A process for producing a carbon-filled ceramic composite material comprising a ceramic matrix and a carbon domain dispersed therein with a carbon domain diameter of from 0.01 to 30 .mu.m and a final carbon content in the ceramic composite material of from 11 to 36% by weight, comprising mixing a ceramic powder and a carbon source wherein said carbon source has a hydrogen to carbon ratio of from 0.2 to 2.0, a nitrogen content .ltoreq.2%, a sulfur content .ltoreq.2%, an average molecular weight of from 100 to 2,000, and is selected from the group consisting of a condensed polycyclic aromatic compound, polycondensed aromatic compound, and a mixture thereof; calcining the mixture at a temperature of from 300.degree. to 600.degree. C. in an inert atmosphere; granulating the calcined mixture; shaping the granules; and sintering the shaped article at a temperature of from 1,200.degree. to 2,300.degree. C.
- 2. A process as claimed in claim 1, wherein said ceramic powder is selected from the group consisting of oxides, carbides, nitrides, borides, and mixtures of two or more thereof.
- 3. A process as claimed in claim 1, wherein said ceramic powder is silicon carbide.
