Formed coke, electrode-grade graphite (E.G.) and elctrode-grade carbon (E.C.) were modified by infiltrating carbon within the pores by use of methane cracking. The rate of oxidation with CO2 was lowered for all these samples but the amount of reduction was dependent on pore structures. Decrease in the rate for the electrode-grade carbon was very large compared to other samples. The mechanism of enhancement of resistance against oxidation was explained in terms of the pore structure changes accompanying infiltration and oxidation.
