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.
