Morphological characteristics of graphite is soft, black and gray; greasy feeling, can contaminate the paper. Hardness of 1 to 2, in the vertical direction with an impurity may be increased to increase its hardness 3-5. Specific gravity of 1.9 to 2.3. The specific surface area in the range of concentrated 1-20m2 / g, in the absence of oxygen, conditions, having a melting point above 3000 ℃, temperature is one of the most minerals. It conductivity, thermal conductivity. Nature there are no pure graphite, which often contain SiO2, Al2O3, FeO, CaO, P2O5, CuO and other impurities. These impurities often appear to quartz, pyrite, carbonate and other minerals form. In addition, water, bitumen, CO2, H2, CH4, N2 and other gases portions. Therefore, the analysis of graphite, in addition to the fixed carbon content was measured, it must also determine the content of volatile matter and ash at the same time. Editing features crystal crystal system and space group: hexagonal, P63 / mmm cell parameters: a0 = 0.246nm, c0 = 0.670nm typical layered structure, a layer of carbon atoms arranged in graphite, each carbon with the adjacent carbon equidistant between connected to each layer of carbon arranged in a hexagonal ring, adjacent layers of hexagonal carbon ring down through the mesh direction displacement parallel to each other and then stacked to form a layered structure of graphite manufacturer, displacement orientation and distance Different leads to different multi-type structure. Between the upper and lower layers of carbon atoms, the distance (within the layer spacing CC = 0.142nm, CC interlayer spacing = 0.340nm) is much greater than the distance between the carbon within the same layer of forms: single crystal often has a graphite sheet or plate products, are rare but complete. Aggregate is usually scaly, massive and earthy colors: black iron Streak: Bright Black Transparency: Opaque Luster: semi-metallic luster hardness: 1-2 cleavage and fracture: a very complete cleavage parallel to gravity: 2.21-2.26 g / cm3 specific surface area: 5-10m2 / g other properties: a flexible sheet, there is a sense of slippery, easy to dirty hands, have good electrical conductivity characteristics identify black graphite iron cylinder, low hardness, a group of very complete cleavage, there slippery sensation and infected hand; if the wetting of zinc sulfate solution on the graphite grains can be precipitated copper spots on graphite similar molybdenite no such reaction column graphite, graphite, carbon Sea Dragon industry provided by the Carbon Co., Ltd.
