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 adjacent to each carbon-carbon equidistant between connected, each layer by hexagonal carbon ring arranged vertically adjacent layers of hexagonal carbon ring through mutual displacement parallel to the direction of the mesh and then stacked to form a layered structure of graphite packing, different displacement direction and distance led to different multi-type structure. Between the upper and lower layers of carbon atoms is much greater distance than the distance between the carbon within the same layer (the inner layer of CC spacing = 0.142nm graphite products, the interlayer spacing CC = 0.340nm) forms: single crystal often has a flaky or board like, but complete rare. 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 graphite sheets, there is a sense of slippery, easy to dirty hands graphite milk, has good electrical conductivity characteristics identify black iron, low hardness, a group of very complete cleavage, There are slippery feeling and stained hand; if wet zinc sulfate solution on the graphite grains can be precipitated copper spots, similar to the graphite does not have this reaction molybdenite ore industry will be divided graphite crystalline (flake) graphite ore and stable crystalline (earthy) graphite ore into two categories. Crystalline flake graphite ores can be divided into two kinds of compact shape. Flake graphite ore to China crystal type, followed by the Aphanitic type, dense crystalline graphite-like Alexis de Puebla saw in Xinjiang, such as individual deposits, little industrial value. Stable crystalline graphite ores typically in microcrystalline aggregates, the crystal grain size of less than 1μm, only under the electron microscope to observe their crystalline form. Ore grayish black, steel gray, usually glossy dark, with a dense block, earthy and layered, pp sheet structure. Process performance is better than implicit polycrystalline graphite flake graphite, industrial application is also smaller, ore grades are generally higher, but poor ore optional. Mineral composition of graphite-based, there are associated andalusite, water mica, sericite and minor pyrite, tourmaline, limonite, calcite. Grade is generally 60 to 80%, ash content of 15 to 22%, volatile content of 1 to 2%, a water content of 2 to 7%. Graphite packing, Sea Dragon Carbon and graphite by Carbon Co., Ltd.
