Graphite

Properties"  Graphite is a layered compound. In each layer, the carbon atoms are arranged in a hexagonal lattice with separation of 0.142 nm, and the distance between planes is 0.335 nm. The two known forms of graphite, alpha (hexagonal) and beta (rhombohedral ), have very similar physical properties (except that the graphene layers stack slightly differently). The hexagonal graphite may be either flat or buckled. The alpha form can be converted to the beta form through mechanical treatment and the beta form reverts to the alpha form when it is heated above 1300 degrees celsus . The layering contributes to its lower density.  The acoustic and thermal properties of graphite are highly anisotropic, since phonos propagate very quickly along the tightly-bound planes, but are slower to travel from one plane to another.  Graphite can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity ). These valence electrons are free to move, so are able to conduct electricity.
