Graphite carbon element is the crystallization of minerals, and its crystal framework for the layered hexagonal structure. Each network layer between the distance of 3.40, the same network layer of carbon atoms in the pitch for 1.42A. A six-crystal system, complete with layered cleavage. Cleavage face key elements to focus on the weak molecular attractive, so Natural floatability of its very good.
Graphite and diamond, the carbon 60, carbon nanotubes are single quality, they are allotrope.
Lacey City, Shandong Province of China's major producing graphite, graphite proved reserves of 6,871,100 tons, is to maintain reserves of 6,399,300 tons.
Soft graphite, and gray; there is a sense of oily, contaminated paper. Hardness of 1 to 2, along with the impurities in the vertical direction to increase its hardness could be increased to 3 to 5. The proportion of 1.9 to 2.3. Surface area on the scope of the 1-20m2 / g (F-Sorb 2400 Miriam BET surface area than the test method), isolated from oxygen conditions, the melting point in more than 3000 ℃, the temperature is one of the mineral.
Nature is not pure graphite, which often contain Si02, A1203, Fe0, CaO, P2O5, Cu0, and other impurities. These impurities are often quartz, pyrite, carbonate minerals, such as the form. In addition, water, asphalt, CO2, H2, CH4, N2, and so part of the gas. Therefore, the analysis of graphite, with the exception of fixed determination of carbon content, but also to be determined at the same time ash and volatile matter content.
The properties of graphite technology mainly on its crystalline morphology. Crystallization of a different form of mineral graphite, have different values and industrial uses.
