Abstract

The present invention relates to methods for producing self-supporting ceramic and ceramic composite bodies having a protective surface region on at least a portion of the surface of the formed bodies, and bodies produced thereby. The protective surface region is formed upon reaction of at least two components of the ceramic or ceramic composite body.
