GRAPHITIC CARBONS CONTAINING INTERSTITICEABLE ELEMENTS ABSTRACT OF THE INVENTION This invention relates to the production of a unique class of granular graphitic carbon materials containing inter- stiticeable elements such as metallic elements dispersed throughout the graphitic structure. More specifically, the unique class of products contain elements that enhance the controlled nucleation of dissolved carbon during the solidi- fication of molten cast irons and are of particular value in the manufacture of quality iron castings. Moreover, the chemical form of the selected interstiticeable elements and their high degree of dissemination within and throughout a graphitic carbon structure has been shown to provide special properties that increase the controlled nucleating or "inoculating" ability of the products of this invention over that obtained by use of the components added individually or in a simple mixture to molten cast iron.
