exfoliated graphite

The product of very rapid heating (or flash heating) of @G02684@ @I03076@, such as @G02684@ hydrogensulfate of relatively large particle diameter (flakes). The vaporizing intercalated substances force the @G02684@ layers apart. The exfoliated @G02684@ assumes an accordion-like shape with an apparent volume often hundreds of times that of the original @G02684@ flakes.
Exfoliated @G02684@ is usually prepared from well-crystallized natural flake @G02684@. It is used for the production of @G02684@ foils. Exfoliated @G02684@ is different from the deflagration product of @G02684@ oxide (graphitic acid).
