In graphite crystal, the carbon atoms in the same layer sp2 hybrid form a covalent bond, each carbon atom covalently linked to three with three other atoms. Six carbon atoms in the same plane as the formation of a regular six-shaped ring again and again, stretching into the lamellar structure of graphite manufacturer, here are all CC bond length 142pm, this is just part of the bond length range atomic crystals, so for the same layer , it is the atomic crystal. Carbon atoms in the same plane but also each of the remaining one p orbital, they overlap each other. Electronic comparison group consisting of graphite, a metal equivalent of free electrons can be thermally and electrically conductive so graphite, which is characteristic of metal crystals. Therefore classified as a metal crystal. Since the carbon atoms arranged in close thermal lattice vibration difficulties in crystallization of graphite atomic layer of graphite to high temperature and thus a special thermal properties. Graphite melting point of 3850 ℃, boiling point of 4250 ℃, heat absorption 6.9036 × 107J / kg, the high temperature arc ignition weight loss is extremely small, the strength is doubled at 2500 ℃ than when normal temperature, small thermal expansion (1.2 × coefficient 10-6), sudden changes in volume when the temperature changed little. Since electrons flow easily in the presence of graphite crystal, and therefore its conductivity, thermal conductivity less than the metal.
