Graphite, C

Graphite (from the Greek graphein "to write") represents another allotrope of carbon besides diamond and fullerene. Graphite is gray to gray-black, non-transparent and has a metallic shine. In nature, crystalline graphite mostly exists in hexagonal but sometimes in rhombohedral form. Compared to diamond, graphite is very soft (HG=1).

Graphite is being used, for example, as lubricant, as material for self-lubricating bearings and gaskets, in pencils, as electrodes in electric arc furnaces, and in the electronical industry.
