ABSTRACT:
A method for the manufacture of high-strength, high-density carbon materials is disclosed. The method comprises the steps of pulverizing a carbonaceous raw material having a carbon content of at least 92% by weight, a volatile content of 7-20% by weight up to 900.degree. C., and linear shrinkage as a molded body of at most 6% during heating up to 500.degree. C. to an average particle diameter of greater than 10 .mu.m and at most 40 .mu.m, followed by molding and baking. An organic fiber after baking in an inert atmosphere at a temperature of at least 400.degree. C. may be mixed with the pulverized carbonaceous raw material.
