In the production of high-density carbon materials directly from a green coke without the aid of a binder by a process comprising molding a finely pulverized green coke as such by pressing in a mold, demolding and baking the molded green coke to form a sintered carbon material and, if desired, graphitizing the sintered material, a serious disadvantage that there occur laminar cracks in the molded green coke at the demolding stage is avoided by molding the green coke in the form of a composition comprising a finely pulverized green coke in intimate admixture with a small amount of water or a certain monohydric alcohol.
