General description
Expandable graphite is a synthesized intercalation compound of
graphite that expands or exfoliates when heated. This material is
manufactured by treating flake graphite with various intercalation
reagents that migrate between the graphene layers in a graphite crystal
and remain as stable species.
If exposed to a rapid increase in
temperature, these intercalation compounds decompose into gaseous
products, which results in high inter-graphene layer pressure. This
pressure develops enough force to push apart graphite basal planes in
the “c” axis direction. The result is an increase in the volume of the
graphite of up to 300 times, a lowering of bulk density, and
approximately a 10-fold increase in surface area.
