2000/4/4· Biotemplating—a new concept for preparation of ceramic composite materials with biomorphic microstructures will be described. Biological carbon preforms (C B ‐templates) were derived from different wood structures by high‐temperature pyrolysis at temperatures between 800 and 1800 C and used as templates for infiltration with gaseous or liquid Si to form SiC‐ and SiSiC‐ceramics.
