exfoliated graphite

https://doi.org/10.1351/goldbook.E02263
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
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).
