Abstract:
An aluminum nitride ceramic is formed by pyrolyzing a poly-N-alkyliminoalane. A ceramic comprising a solid solution of silicon carbide and aluminum nitride is also formed by mixing a preceramic organosilicon polymer with a polyalkyliminoalane and pyrolyzing the mixed polymers composition to ceramic form.
Process For Providing A Protective Oxide Coating On Ceramic Fibers
Thermally stable ceramic fibers are provided by pyrolysis of organosilicon preceramic polymeric fibers to ceramic form and contacting the ceramic fibers with an oxygen-containing gas so as to oxidize the surface of the fibers and form an in-situ oxide coating.
