ABSTRACT:
The present invention relates to self-supporting ceramics or ceramic composite bodies which include a polycrystalline ceramic material comprising the oxidation reaction product of a silicon parent metal with a nitrogenous oxidant, including a nitrogenous vapor-phase oxidant, and optionally, one or more metallic constituents dispersed throughout the polycrystalline ceramic material. A barrier means comprising, for example, at least one of titanium nitride, zirconium nitride, aluminum nitride and boron nitride or a barrier means that has undergone chemical changes or alterations may be removably attached to the self-supporting ceramics or ceramic composite bodies of the present invention.
