Abstract
A number of chemical reactions of graphite have been followed by kinetic studies on single crystals and by simultaneous microscope and electron microscope studies of the surface structure. The reactions studied include reactions with CO2, O2, O3, O, and a preliminary study of the sublimation process. For any one of these reactions, the effect of crystal perfection, previous heat treatment, previous neutron or gamma irradiation, and partial annealing of the ensuing radiation effects were studied. Furthermore, the effects of catalysts and of inhibitors on each reaction were examined. Most of the electron microscope studies were carried out by shadowing and replicating the graphite crystals. A method was also developed of preparing plane parallel or wedge-shaped single crystal fragments sufficiently thin for direct examination in the electron microscope. Some observations related to dislocations and radiation damage in these will be discussed.
