✦ Synopsis

A kinetic model has been developed which accurately represents the kinetics of the oxidation of a thin film of pyrolytic carbon at a total pressure of about 100 Pa in the temperature range 748-898K. The two most important features of the mechanism are the existence of at least two distinct types of active site on the carbon surface and the importance of interaction of the oxide complex formed at these sites with a molecule of oxygen. The reactivity of the oxide complex is also dependent on the nature of the carbon site to which the oxygen is bound. The model is consistent with the main features of more general models of carbon oxidation in the literature.
