Exist in the form of carbon is varied, there is crystalline elemental carbon such as diamond, graphite; amorphous carbon such as coal; complex organic compounds such as animals and plants and the like; carbonates such as marble and the like. Physical and chemical properties of elemental carbon depends on its crystal structure. High hardness of diamond and graphite soft creamy different graphite crystal structure, each with its own appearance, density, melting point. Graphite crystals with a typical layer structure of carbon atoms arranged in a hexagonal mesh-like layer, the carbon atoms on the surface network node with respect to the center of the upper and lower adjacent layers of the grid. Repeat for a two layered graphite 2H polytype, is hexagonal, which is commonly referred to graphite; if repeated layered graphite compared to 3 3R polytype, trigonal system, but not in the natural graphite structure isolated separately. In graphite crystal structure, the coordination number of the inner layers of carbon atoms is 3 graphite emulsion, a covalent metal bond, spacing 0.142nm Qingdao graphite manufacturers to molecular bond between the layers is connected to a pitch of 0.340nm, such special The crystal structure and chemical bonding of the graphite has some special process performance.
