PURPOSE:To accomplish continuous molding of the title parts of product shape without mold attachment of molding powder by granulating self-sinterable raw material powder for carbonaceous material production through the addition of a specific releasant followed by molding and baking. CONSTITUTION:In the production of a carbonaceous material where selfsinterable raw material powder for carbonaceous material production is granulated, molded and then baked and furthermore, if needed, graphitized, a releasant <=470 deg.C in the temperature giving its maximum thermal decomposition rate is added to the above raw material in its granulation. Said raw material powder means (A) a product obtained by blending raw material aggregate and binder followed by hot kneading and then grounding, (B) mesocarbon microbeads, (C) ground product of mesocarbon microbeads, or (D) mixture thereof, which can give carbonaceous material when molded and baked. And the temperature giving the maximum thermal decomposition rate means such a temperature that the thermal decomposition rate determined by thermally differentiating the weight loss at the heat treatment of the releasant in a non- oxidative atmosphere up to 600 deg.C becomes maximum at >=200 deg.C. |
