摘要
A carbonaceous article, e.g., a carbon or graphite electrode, is provided with an oxidation prohibitive coating comprising a compliant, low strength, porous, sintered, particulate, refractory, ceramic material. A cover layer is preferably applied over this compliant, low strength, ceramic layer, the cover layer comprising a rigid, glassy substance which is plastic and flowable at temperatures above about 750 DEG C.
