PURPOSE:To manufacture a dense and homogeneous precision molded article of hard carbonaceous material, easily, rapidly, without necessitating the secondary processing, by dispersing a polymeric compound uniformly in fine carbon powder, applying mechanical energy to the dispersion, and subjecting the product to the forming process, the treatment for making infusible, and the baking process. CONSTITUTION:A binder selected from a monomer, prepolymer and/or oligomer of a polymeric compound, exhibiting high carbon residue yield after baking and easily polymerizable by heat, e.g. vinyl chloride, etc., is dispersed uniformly in fine carbon powder. Mechanical energy is applied to the dispersion to induce the mechanochemical phenomenon and to bond the binder to the surface of the particles of the fine powder. The product is used as a molding composition, formed to a desired form, made infusible, and baked under a definite condition. A precision molded article of hard carbonaceous material, such as a round rod having smooth surface and high precision can be manufactured easily, without necessitating the secondary processing. |
