The product of very rapid heating (or flash heating) of
graphiteintercalation compounds, such as
graphite hydrogensulfate of relatively large particle diameter (flakes). The vaporizing intercalated
substances force the
graphite layers apart. The exfoliated
graphite assumes an accordion-like shape with an apparent volume often hundreds of times that
of the original
graphite flakes.
Note:
Exfoliated
graphite is usually prepared from well-crystallized natural flake
graphite. It is used for the production of
graphite foils. Exfoliated
graphite is different from the deflagration product of
graphite oxide (graphitic acid).
