THE OXIDATION OF PYROLYTIC GRAPHITE AT VARIOUS TEMPERATURES AND AIR VELOCITIES

Abstract

The oxidation kinetics of pyrolytic graphite was studied as a function of time, temperature, and air velocity. It was found that the oxidation of pyrolytic graphite is controlled by chemical activity below 1600 deg F. At 1600 deg F and above, the reaction is under diffusion control and the reaction rate is proportional to the 0.4 power of the air velocity. Oxidation proceeded preferentially in the "a" direction and is attributed to the weaker bonding between planes.
