PURPOSE:To eliminate disadvantageous problems caused in the molding state due to seasonally changing factors and to provide isotropic carbon material having always high quality by molding carbonaceous molding powder and/or rubber case for molding which has been conditioned at a specified temp., then, calcining and graphitizing the molding powder or the rubber case. CONSTITUTION:The temp. of pulverized carbonaceous molding material to <=500mum maximum particle size and 40-80mum mean particle size is conditioned at 10-40 deg.C, then, the powder is packed, if necessary, in a rubber case conditioned at 10-40 deg.C. Then, the inside of the rubber case is evacuated to remove the air or other gas included in the molding powder, and the rubber case is sealed tightly and the powder is press-molded isotoropically with a cold hydrostatic press to a desired shape to obtain a green molded body of carbon. Further, the molded body is calcined at ca. 1,000 deg.C, then graphitized at >=2,500 deg.C. |
