Sea Dragon graphite milk _ _ Carbon graphite provided by Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd. Weifang Sea Dragon (www.longmentanye.com) is specialized in the "graphite" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Chin. Graphite is a crystalline mineral carbonaceous elements, its crystalline lattice is hexagonal layered structure. Each network distance between the layers of 340pm, the same pitch in the 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 graphite milk, is hexagonal, which is commonly referred to graphite; if repeated three layered graphite compared 3R polytype carbon graphite, graphite trigonal system, but can not be separated individually in natural graphite structure. In graphite crystal structure, the coordination number of the inner layers of carbon atoms is 3, with a covalent bond metal, 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.
