Morphological characteristics of graphite soft roughness graphite, 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. Besides graphite, there water, bitumen, CO2, H2, CH4, N2 and other gases portions. Therefore, the analysis of the graphite graphite Lacey, in addition to the fixed carbon content was measured, it must also determine the content of volatile matter and ash at the same time. In the case of graphite microstructure observation: 1 without the use of pearlite stabilizer, can greatly increase the percentage of ferritic ductile iron, with respect to the use of ordinary petroleum coke increased by 10% -15% on average with respect to the ink ball 2 improve the shape, the number of ink ball up to 400% increase, can be reduced to a large extent the amount of inoculant for expensive post-trimming and significant cost reduction. In addition the recarburizer prices due to high carbon graphite sulfur can be fully absorbed, not anti-slag, slag processes and reduce the cost of the ball, shorten the melting cycle, saving energy consumption. _ _ Sell graphite graphite carbon industry is provided by the North Sea Dragon Sea Dragon Carbon Co., Ltd.
