Graphitizable carbon stacking order

However, the stacking order of the graphitizable carbons from pitch is established via the formation and stacking of lamellar, nematic liquid crystals and mesophase from the isotropic fluid phase of the pitch carbonization (Section 2.7), such graphitizable carbons having relatively low surface areas (< 5 m g ). Hence, a gasifying gas has almost zero opportunity to penetrate the interior of a carbon and gasification will dominantly take place at external surfaces.
