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.
Abstract:
Method for producing a protective layer by subjecting a ceramic or a ceramic composite body being interconnected residual metal therein to a particular atmosphere, a protective layer can be formed from the interconnected metal. Such a layer can be protective, especially in corrosion environments which include various gaseous or solid species containing sodium and silicon, such as those found in glass tanks.
