Abstract
This invention relates to the production of a unique class of granular graphitic carbon materials containing 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 solidification of molten cast irons and are of particular value in the manufacture of quality iron castings. Moreover, the chemical form of the selected metallic 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.
