A process for producing graphite grains, characterized by graphitizing carbon black by induction heating. A process in which at least one element selected from metals, boron and silicon is contained in graphite grains is preferable. Refractories obtained by molding a composition containing a refractory filler and the graphite grains produced by the foregoing process are excellent in thermal shock resistance, oxidation resistance and corrosion resistance. Consequently, a process for producing graphite grains in which the graphitization of carbon black that requires quite a high temperature in an ordinary heating method can easily proceed is provided. Further, refractories excellent in thermal shock resistance, oxidation resistance and corrosion resistance and having a low carbon content are provided. |
