Graphite in chemistry

WebOne famous intercalation host is graphite, which intercalates potassium as a guest. [3] Intercalation expands the van der Waals gap between sheets, which requires energy. Usually this energy is supplied by charge transfer between the guest and the host solid, i.e., redox. Two potassium graphite compounds are KC 8 and KC 24.
