Manufacture of carbonaceous material of high density and low elasticity

Abstract

Abstract PURPOSE:To obtain easily a high density carbonaceous material with low elasticity by adding a material formed by expanding natural graphite granules to a mixture of a carbonaceous material with a binder, kneading them, and molding and calcining the kneaded material. CONSTITUTION:To a mixture of a carbonaceous material with a binder is added about 1-30wt% expanded graphite formed by expanding natural graphite granules by immersion in a strong oxidizing soln. or other method. They are kneaded, and the kneaded materialis molded, calcined, and optionally graphitized to obtain a molded body of a carbonaceous material or a graphitic material. By this method a high density carbonaceous material with low elasticity suitable for use as a sealing material, an electric brush, etc. is obtd.
