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 a lamellar structure carbon graphite factory, 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 a p-orbital graphite each remaining milk price, they overlap each other. Electronic relatively free, equivalent metal free electrons, so the graphite can be thermally and electrically conductive, which is characteristic of metal crystals. Therefore classified as a metal crystal. Because graphite has many excellent properties, and thus in the metallurgical, mechanical, electrical, chemical, textile, defense and other industries widely used. Can be used for refractories. Graphite flake graphite products to maintain the original chemical properties but also has a strong self-lubricating properties. Characteristics of the graphite powder, i.e. the acid resistance of high strength, corrosion resistance and high temperature and low temperature 3000 ℃ -204 ℃, while its compressive strength is greater than 800kg / Cm2 graphite emulsion, and antioxidant, a 1% weight loss in air at 450 ℃, back bomb was 15-50% (density of 1.1-1.5). So graphite products has been widely used in metallurgical, chemical, petrochemical, high-energy physics, aerospace, electronics and other areas.
