Abstract
Novel oxide coatings which can be conveniently applied to reinforcing fibers such as silicon carbide fibers, and which when introduced as a fiber coating into fiber reinforced ceramic matrix composites provide composites exhibiting improved resistance to embrittlement at high temperatures, are described. Oxides effective to provide the improved composites in accordance with the invention include CeO.sub.2 and ZrO.sub.2.
