The product of very rapid heating (or flash heating) of
graphite
intercalation 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
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).
