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 orienta

โฆ Synopsis
The orientation dependence of the small angle scattering by pyrolytic graphite has been investigated. The intensity can be interpreted in terms of the scattering by voids whose shape is oblate ellipsoids of revolution with semi-major and semi-minor axes of a and b respectively. The scattering in the Guinier region is equivalent to that of a dilute dispersion of oriented "Guinier spheres" whose radius is H\l$(a2sin2 y + b2cosZ~)"2, where y is the angle between b and the scattering vector h.
