ABSTRACT:
The present invention relates to a method for producing a protective layer on a ceramic or a ceramic composite body. Stated more particularly, 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.
