Causes and occurrence: graphite is formed at high temperatures. Is the most widely distributed metamorphic graphite deposit, rich in organic matter by the Department or carbonaceous sedimentary rocks formed by regional metamorphism China: Lacey City, Shandong Province, one of the important producer of graphite, graphite graphite wholesale 6.8711 million tons of proven reserves, cash reserves of 6,399,300 tons. Another one is the graphite origin Panshi, graphite reserves of 5 million tons. World: Famous Origin: New York Ticonderoga, Madagascar and Ceylon, our Heilongjiang Jixi Liu Mao was the largest producer. Graphite crystals having a layered structure typical price of graphite, carbon atoms arranged in a hexagonal mesh-like layer, the carbon atoms on the surface network node with respect to the center of the upper and lower adjacent layers of the grid. Repeat for a two layered graphite 2H polytype, is hexagonal, which is commonly referred to graphite; if repeated layered graphite compared to 3 3R polytype, trigonal system, but not in the natural graphite structure isolated separately. In graphite crystal structure, the coordination number of the inner layers of carbon atoms is 3, with a covalent bond of metal, graphite spacing 0.142nm picture, is connected to the molecular bonds between the layers, and pitch is 0.340nm, such a special crystal structure and chemical bond between the graphite has some special process performance. Graphite is mainly used in metallurgical industry refractories; used as a mold and rust paint in the casting industry; for the production of carbon electrodes, carbon rod electrodes, graphite batteries in the electrical industry, made of graphite milk can be used as a TV CRT coating machine, made of carbon products can be used in generators, motors, communications equipment, and many other aspects. Used as aircraft, ships, trains and other high speed machinery lubricant machinery industry; for the manufacture of a variety of anti-corrosion utensils and equipment in the chemical industry; used as nuclear reactor neutron moderator and protection in the nuclear industry materials; in the aerospace industry to do rocket engine tailpipe Throat, rockets, insulation, heat-resistant material and a radio connection and conductive structural material satellite signals on the missiles.
