ABSTRACT:
An oxide barrier coating for a reinforcing fiber is provided with a preselected microstructure and thickness through control of the concentration of metal salt in heat decomposable form as a precursor of metal oxide. In one form, the salt is a metal oxyhalide salt such as zirconium oxyhalide or hafnium oxyhalide. Fibers, such as ones of alumina, aluminasilicate or silicon carbide, having the coating of the invention are especially useful as reinforcing fibers for reinforced ceramic matrix composites.
