SURFACE AREA EFFECTS ON THE OXIDATION KINETICS OF PYROLYTIC GRAPHITE

Abstract

The oxidation kinetics of pyrolytic graphite was studied as a function of temperature, air velocity, and surface area. The transition temperature between chemical and diffusion control may be significantly increased or decreased by decreasing or increasing the surface area of pyrolytic graphite. Kinetic theory calculations showed that the maximum reaction rate in the diffusion-controlled region is 50,000 times the observed rate for specimens having the smallest surface area.
