    Abstract: Articles of manufacture having a graphitic body are encased by a porous, fluid-permeable, continuous casing of individual siliconcarbide-encased graphite particles which are diffused into and integral with the entire outer surface of the graphitic body. This casing is produced by forming a silicon monoxide vapor, by the reaction of silicon and silicon dioxide powders, for example, which vapor in turn is diffused into the graphitic body and reacted with graphite particles near the surface of the graphitic body to form, in situ, the individual silicon carbide casings that constitute the continuous casing of the entire outer surface.
