PROPERTIES AND CHARACTERISTICS OF GRAPHITE
Thermodynamically graphite at atmospheric pressure is the more stable form of carbon. Diamond is trans-formed to graphite above 1500 C Figure 1-4 . The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms. The ideal graphite structure is shown in Figure 1-5.

Natural Flake Graphite Asbury Carbons
For instance “run of mine” flake graphite from Madagascar is typically 85-90% carbon with the balance ash. Graphite from Canada runs 90-97% carbon and graphite from China 90-96% carbon. Careful control of the floatation methodology can generally improve the purity but floatation cannot reduce the level of “intercalated” mineral matter.
