Abstract
A method of making shaped bodies of silicon carbide, of graphite coated with silicon carbide or of a graphite-like material with a silicon carbide surface wherein a graphitic body is assembled from preformed parts in the desired shape and is immersed, under a chemically inert atmosphere, in a silicon melt and after penetration of the melt into gaps between abutting surfaces of the body and after reaction of the silicon with the graphite or the graphite-like material to form silicon carbide at the junctions, the body is removed from the melt and is cooled in a chemically inert atmosphere.
