The Influence of Crystal Plane on Graphitization of Diamond by Structure Analysis

Abstract:

Under atmospheric pressure diamond is a metastable phase of carbon, which on heating can spontaneously transforms into a thermodynamically stable phase of carbon, graphite. No matter in diamond and in graphite, the six-fold ring is the smallest ring structure; they are very simillar in shape. The graphitization occurs when the rings of {111} plane are flattened. The {111} plane of diamond is the one that would graphitize preferentially and the (001) planes are most resistant to high temperature thermal graphitization.
