Graphite consists of a ring of six carbon atoms closely bonded together hexagonally in widely spaced layers. The bonds within the layers are strong but the bonds between the layers are less in number and therefore are weaker. Graphite is the stable form of carbon – diamonds at or near the Earth's surface are gradually changing to graphite.

Graphite has not been mined in the United States since the 1950s; deposits are too small and not of a high enough grade.
