Patent ID: 7682534

Claim:
Method for producing a ceramic component based on carbon, comprising the steps of: obtaining a cellulose-containing, semi-finished, sheet-shaped molded piece having a density ρ with ρ≧800 kg/m 3 and a homogeneous density distribution across its sheet diagonal line with a density deviation Δρ wherein Δρ≦20 kg/m 3 , pyrolyzing the molded piece at a temperature T with 400° C.≦T≦2300° C. in a non-oxidizing gas atmosphere, to obtain a pyrolyzed component having a density of about 700 to 900 kg/m 3 , and subjecting the pyrolyzed component to a siliconization operation to achieve an SiSiC ceramic body with a desired free C portion of close to 0%.
