Expandable graphite

The layered lattice structure of graphite enables the intercalation of atoms or small molecules between the carbon layers. This results in so-called expandable salt or GIC (Graphite Intercalation Compound). High-quality expandable graphites have a high proportion of intercalation layers, with the molecules incorporated generally being sulphur or nitrogen compounds. One of the most important applications of expandable graphite is its use in flame retardants.
