Graphite most seen marble, schist or gneiss, organic carbonaceous material causes deterioration from. Seams can be formed by thermal metamorphism disseminated graphite parts. Graphite is a small amount of primary igneous minerals. Graphite is also common in meteorites, who is lumpy in appearance certainly cube orientation relationship between the composition of the assembly body said polycrystalline cubic graphite. The most widely spread is the metamorphic deposits graphite graphite, the Department of the rich in organic matter or carbonaceous sedimentary rocks formed by regional metamorphism disseminated; famous origin of New York Ticonderoga, Madagascar and Ceylon, of China's Heilongjiang Jixi Liu Mao was the largest producer. Editing features crystal crystal system and space group: hexagonal carbon graphite products prices, P63 / mmm cell parameters: a0 = 0.246nm, c0 = 0.670nm typical layered structure, the carbon atoms are arranged into layers, each carbon equidistant between adjacent carbon and connected to each layer of carbon arranged in a ring by Qingdao hexagonal graphite products prices, the carbon adjacent to the upper and lower layers of hexagonal rings parallel to each other through a mesh surface displacement direction and then stacked to form a layered structure, heading and distance displacement leads to various different polytype 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 sheet or plate, 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: Lacey flexible graphite sheets with the company, there is a sense of slippery, easy to dirty hands, have good electrical conductivity characteristics identify black iron, low hardness, a group of very complete cleavage There slippery sensation and infected hand; if wet zinc sulfate solution on the graphite grains can be precipitated copper spots on graphite similar molybdenite company does not have this reaction carbon graphite, graphite North Sea Dragon by Carbon Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd.
