Applications |
|
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.
Graphite Central 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.
