A method for producing graphite structures which are of light weight and excel in elasticity from a carbonaceous material comprises in succession the steps of: (a) treating said carbonaceous material with nitric acid or a nitric-sulfuric acid mixture, (b) bringing the acid-treated carbonaceous material into contact with a basic aqueous solution to make it soluble, (c) adding an acidic aqueous solution to the obtained soluble matter to regulate the pH of said soluble matter to 3 or less, thereby precipitating a carbonaceous component therefrom, and (d) graphitizing the thus precipitated carbonaceous component at 2,400.degree.C or higher temperature. |
