Method for the production of a carbon or ceramic component

Method for producing a ceramic component based on carbon, comprising the steps of:

• obtaining a semi-finished molded piece produced from wood or plant fibers in the form of a fiber, chip or strand-containing board having a density ρ with ρ≧800 kg/m3 and a homogeneous density distribution across its sheet diagonal line with a density deviation Δρ wherein Δρ≦20 kg/m3;
• pyrolyzing the semi-finished molded piece at a temperature T with 400° C.≦T≦2300° C. in the absence of oxygen;
• removing gaseous volatile compounds released during the pyrolysis with an inert gas flow,
• to obtain a pyrolyzed component having a density of about 700 to 900 kg/m3;
• 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%.
