PURPOSE:To decrease scattering of dust from an electrode at its cut molding further enable the electrode to be less consumed, by impregnating the whole surface or a required part of the carbon electrode with a conductive material of metal, metallic salt, graphite, etc. CONSTITUTION:A mixture of structural material and binding material, being primarily and secondarily sintered by the method of sintering a graphite material, forms a porous carbon material of specific gravity about 1.5-1.7g/cm<3>. Next, the porous carbon material as in the above is impregnated with a conductive material of metallic fine particle, graphite fine particle, etc. mixing with tar, synthetic resin, etc. The impregnated carbon material as obtained in the above, decreasing the generation of dust when an electrode is cut and molded while preventing an environment from contamination due to scattering of the dust in the periphery, easily molds the electrode. While the carbon material can be impregnated with metal on a surface of the electrode molded into a predetermined shape. |
