Graphite or light in glass and paper polishing agents and rust inhibitors, manufacture pencils, ink, black ink and synthetic diamond materials. With the development of modern science and technology and carbon graphite industry, graphite applications is constantly expanding, and has become an important raw material for the high-tech field of new composite materials, has an important role in the national economy. 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 layer 2 is 2H polytype, is hexagonal, which is commonly referred to graphite graphite; if repeated three layered graphite compared 3R polytype graphite milk, trigonal system, but in the natural graphite structure alone can not be separated. Graphite in a graphite crystal structure in the milk price, the coordination number of the inner layers of carbon atoms is 3, with covalent metal 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 the graphite has some special process performance.
