摘要：
A method for the production of a carbon or a ceramic component based on carbon, using a cellulose-containing semi-finished molded piece which is pyrolyzed. According to the invention, homogeneous large-size ceramic components may be produced, whereby a cellulose-containing, semi-finished molded piece containing fibers, chips or strands of homogeneous density distribution and homogeneous structure is used as semi-finished molded piece and is pyrolyzed in non-oxidizing gas atmospheres.
