Abstract
There is provided a method for producing a graphite material and a graphite material produced by the method The method includes a kneading step of adding a hydrophobic binding material to a first carbonaceous raw material containing coke powder, followed by heat kneading to obtain a mixture, a pulverizing step of pulverizing the mixture obtained in the kneading step to obtain a second carbonaceous raw material, a granulating step of obtaining a granulated powder using the second carbonaceous raw material obtained in the pulverizing step, a hydrophilic binding material and a solvent, a molding step of subjecting the granulated powder obtained in the granulating step to cold isostatic press molding to obtain a molded body, a burning step of burning the molded body obtained in the molding step to obtain a burnt product, and a graphitizing step of graphitizing the burnt product obtained in the burning step.
