✦ 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.

## Abatrac& -The influence of ambient gas phase on the graphitixation rate of carbons was investigated. A calcined petroleum coke was heat treated in a high purity graphite tube furnace for various residence times at a maximum temperature ranging from 1900"-2400°C under air pressure of 4, 2 and 0.
