โœฆ Synopsis

Samples of highly oriented pyrolytic graphite reacted with oxygen under various conditions have been studied using optical microscopy and both transmission and scanning electron microscopy. In this manner the effects of oxidation on basal and edge surfaces have been separately evaluated. The orientation and depth of etch pits have been determined. 77.

). The scanning electron microscope was used to examine pyrolytic graphite oxidized by oxygen above 600ยฐC. "Faces" sometimes contain circular holes and sometimes appear to be oxidized smoothly. Layers appear to resist oxidation to different degrees. "Edges" show separation of layers which are attacked on edges but also on exposed surfaces normal to the preferred c-direction, Some edges also show a smooth surface after oxidation.

Highly oriented samples of well graphitised pyrolytic graphite have been irradiated to doses of 2.5 X 102\* n.v.t. (Dido Equivalent Dose) at temperatures between 250ยฐC and 470ยฐC. Measurements have been made of the changes in dimensions parallel and perpendicular to the deposition planes, density, t
