Natural graphite

Natural graphite Natural graphite is a metal. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers.

The natural crystals have a typical shape of ~0.1 cm, and have a metallic appearance. A selection of peer review publications on the natural graphite can be found below.
