ABSTRACT:
Acid-treated and water-washed graphite particles are further treated with an aqueous solution of a phosphoric acid or a salt thereof, the expanded by heating to 20 to 70 times (in terms of bulk density ratio) the original graphite particles and the expanded particles are pressure-molded to obtain a graphite material having compressibility and recovering property and suitable for use in making those gaskets, packings, heat insulators, and cushion elements which are resistant to oxidation and serviceable at high temperatures.
