GraphiteGraphite is a soft, crystalline polymorph of carbon, and while it shares the same chemistry as diamond the two have very different physical properties (see diamond for examples). Graphite exhibits both metallic and non-metallic properties. The metallic properties include thermal and electrical conductivity, while the non-metallic properties include inertness, high thermal resistance, and lubricity. Some of the major end uses of graphite are in high-temperature lubricants, brushes for electrical motors, friction materials, battery and fuel cells, and pencil "lead".
