More Information
Summary:The present invention relates to a production method for a carbon material, the production method being characterized by including an oxidizing step for oxidizing ashless coal, a molding step for combining and molding unoxidized ashless coal and the oxidized ashless coal obtained in the oxidizing step, and a carbonizing step for carbonizing the molded body obtained in the molding step. The production method is also characterized by the rate of oxygen increase of the oxidized ashless coal obtained in the oxidation step being 2.0-10.0% and by the mixing ratio of the oxidized ashless coal during the molding step being 60-95 parts by mass in relation to 100 total parts by mass of the oxidized ashless coal and the unoxidized ashless coal. A high-purity and high-density carbon material can thereby be produced by said method.
