Expandable graphite
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.

Applications |

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.
BariteWorld’s expandable graphite is used as a fire suppressant intumescent additive, as a raw material to manufacture graphite gasket products, as an electrically conductive filler, as a foundry additive, and in a wide variety of other industrial applications.
