A method for determining the degree of orientation of graphite

Abstract

Abstract The preferential orientation of the carbon planes in blocks of graphite prepared by extrusion or pressing is described in terms of an orientation function and it is shown how this varies with the particle size of the starting materials. An ‘anisotropy factor’ is defined as a useful index of the material. A discussion is given of the effect of orientation on the anisotropy of thermal and irradiation expansion of bulk graphite.
