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.

"Graphite exfoliation by supercritical carbon dioxide ...

Supercritical carbon dioxide is used to exfoliate graphite, producing a small, several-layer graphitic flake. The supercritical conditions of 2000, 2500, and 3000 psi and temperatures of 40°, 50°, and 60°C, have been used to study the effect of critical density on the sizes and zeta potentials of the treated flakes. Photon Correlation Spectroscopy (PCS), Brunauer-Emmett-Teller (BET) surface ...
