What Are the Uses of Graphite? | Sciencing

Graphite occurs naturally as flakes and veins within rock fractures or as amorphous lumps. The basic crystalline structure of graphite is a flat sheet of strongly bonded carbon atoms in hexagonal cells. Called graphenes, these sheets stack above each other to create volume, but the vertical bonds between the sheets are very weak.
