Initially synthetic diamond particles were black graphite milk, 0.5mm size, weighing about 0.1 kt (for gem diamonds can not be less than 0.1 kt individual minimum). United States, Japan, etc., have made 6.1 Klado diamond, synthetic diamond companies at the moment our company Huanghe Whirlwind test test chamber innate mercy of large particles up to 8mm diamond graphite, representing our country at the forefront of the scale studies. We say that a diamond from graphite fly, gem-quality synthetic diamonds in the near future will be supplied to the market. 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, graphite specification condition, 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.
