PURPOSE:To obtain a carbon material having a given constitution ratio without requiring a binder component, by subjecting aggregate coke powder having given particle diameter dispersed in tar to solvent extraction by the use a solvent having lower solubility power than that of quinoline. CONSTITUTION:Aggregate coke is ground into <=10mu particle diameter. A solvent having lower solubility power in tar and pitch than that of quinoline is prepared. The ground coke is uniformly dispersed into the tar and pitch and extracted with the solvent. Aggregate coke having 5-30pts.wt. quinoline soluble component based on 100pts.wt. of the coke is obtained. The quinoline soluble component contains a benzene insoluble component and a benzene soluble component and 5-50pts.wt. soluble component is contained based on 100pts.wt. insoluble component. |
