Graphite is an allotrope of carbon, graphite elements, surrounding each carbon atom linked with three other carbon atoms (the arrangement of a plurality of hexagonal honeycomb form) is covalently bonded to form a covalent molecule. Since each carbon atom will emit an electron, those electrons can move freely graphite machining, graphite and therefore belong to the conductor. Graphite is one of the softest mineral, and its uses include the manufacture of pencil lead, and a lubricant. Carbon is a non-metallic element in the group IVA of the periodic table of the second cycle. Latin for Carbonium, meaning "coal, charcoal," character "C" word by word plus stone charcoal "charcoal" word next to the structure, from the "charcoal" pronunciation. Back in the 1930s, China's Heilongjiang Jixi Liu Mao, Shandong Nanshu graphite graphite mine began production and processing. Beneficiation process was simple, poor working conditions of workers, productivity is very low, only a few thousand tons of annual output. After decades of development, China's carbon and graphite products yield rapid increase in graphite gaskets, graphite 2004-2011 prices, graphite and carbon products production CAGR of 22.12% molecular structure. 2011, China's production of carbon and graphite products 25,561,700 tons, an increase of 21.98%.
