METHOD FOR PRODUCING A CERAMIC SUBSTANCE FOR A CERAMIC MATERIAL

摘要

A method for producing a ceramic substance includes producing a homogeneous mixture containing carbon fibers having a fiber length distribution of D5=<15 mum and at least one powdery and carbonizable binder. The homogeneous mixture is compacted under the action of pressure. The compacted homogeneous mixture is thermally treating for carbonizing, or for carbonizing and graphitizing, to obtain a carbon substance. The carbon substance is siliconized to obtain a ceramic substance.
