Summary

Following our detection of films of elemental carbon in the Hi-NicalonTM\BN\SiC composite and its deleterious effect on oxidative durability, we have examined other SiC\BN\SiC systems. The problem is pervasive, and significant residues of free carbon are confirmed in SylramicTM\BN\SiC materials. Effective techniques for routine detection and characterization of adventitious carbon in SiC\BN\SiC composites are discussed.
