METHOD FOR PRODUCING GRAPHITE MATERIAL, AND GRAPHITE MATERIAL
PROBLEM TO BE SOLVED: To provide a graphite material which allows an anisotropic ratio of the whole base stock thereof to be made lower and which has high isotropy.SOLUTION: A method for producing the graphite material comprises: a kneading step of adding a hydrophobic binding material to a coke powder-containing first carbonaceous raw material and heating/kneading a binding material-added raw material to obtain a mixture; a crushing step of crushing the mixture obtained at the kneading step to obtain a second carbonaceous raw material; a granulating step of granulating the second carbonaceous raw material obtained at the crushing step together with a hydrophilic binding material and a solvent to obtain granulated powder; a molding step of subjecting the granulated powder obtained at the granulating step to cold hydrostatic pressure molding to obtain a molding; a firing step of firing the molding obtained at the molding step to obtain a fired product; and a graphitizing step of graphitizing the fired product obtained at the firing step.
【課題】素材全体の異方比を低減し,等方性の高い黒鉛材を提供する。【解決手段】本発明の黒鉛材はコークス粉末を含む第１の炭素質原料に疎水性結合材を添加し加熱混練して混合物を得る混練工程と、前記混練工程で得られた混合物を粉砕し第２の炭素質原料を得る粉砕工程と、前記粉砕工程で得られた第２の炭素質原料と親水性結合材と、溶媒とを用いて造粒粉を得る造粒工程と、前記造粒工程で得られた造粒粉を冷間静水圧成形して成形体を得る成形工程と、前記成形工程で得られた成形体を焼成し、焼成体を得る焼成工程と、前記焼成工程で得られた焼成体を黒鉛化する工程とを含む。【選択図】図３
