Graphite is a crystalline mineral carbonaceous elements, its crystalline lattice is hexagonal layered structure. Each network distance between the layers of graphite for 340pm company, spacing the same network layer of carbon atoms is 142pm ;. Is a hexagonal system, complete with layered cleavage. Molecular bond cleavage planes mainly on molecular attraction is weak, so the natural floatability well. 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 2 layered graphite 2H polytype graphene price, is hexagonal, which is commonly referred to graphite; if repeated layered graphite as compared 3R polytype, trigonal system, but in the natural graphite 3 structure alone can not be separated. In graphite crystal structure, the coordination number of the inner layers of carbon atoms is 3 graphite, metal having a covalent bond, spacing 0.142nm, a molecular bond between the layers is connected to a pitch of 0.340nm, such a special crystal structure and chemical bonding of graphite has some special process performance. According to the ideal graphite sample Bernard provided, graphite structure is a plurality of parallel to the base surface level of oil continuous composite made. Within each layer, the carbon atoms are arranged in hexagonal, three adjacent carbon atoms covalently bonded to, a two dimensional infinitely extended into a mesh plane graphite products, known as the base surface. Stacked sequentially phase shifted base surface, as shown in FIG. Unit cell a = 2.4612 ± 0.00001 ?, e = 6.7079 on 0.0007 ?. Interlayer distance: 3.3538 ?, capacity: 35.190 ?. Atoms, 4. Second Density: 2.266 g / cm, the same position every layer of carbon atoms, becomes AB, AB, AB. . . The three-dimensional ordered, was dense hexagonal stacking. Therefore, graphite on crystallography classification is hexagonal. Each layer is a metallic bond between the force against the activity level electron cloud between the link provided together, an interlayer distance of 3.35.8 angstroms, the binding energy of 4.36 kcal / g-atom, it is a very small change with temperature, by a 4 kcal of 196 degrees / gram atom to 3.6 kcal of 1118 degrees / gram atom, and the atom on the same plane spacing 1.415 ?, their binding ability to 170 kcal / gram atom. Each unit cell has four carbon atoms. Graphite Company, the North Sea Dragon Carbon (certified), graphite is provided by Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd.
