Graphite Production Process

Intercalation. Due to its extreme anisotropy, the graphite crystal enables salts to be intercalation in its structure. When heated, these salts evaporate, causing the disruption of inter-planar connections, "expanding" the graphite. Nacional de Grafite developed graphite intercalation and expansion processes compatible with the environment.
