Back in the 1930s, China's Heilongjiang Jixi Liu Mao, Shandong Nanshu graphite graphite mine began production and processing. Beneficiation process was simple graphite mold, poor labor conditions, low productivity ultrafine graphite, only a few thousand tons of annual production. After decades of development, China's production of carbon and graphite products rising rapidly, 2004-2011, graphite and carbon products production CAGR of 22.12% molecular structure. In 2011, China's production of carbon and graphite products to 25,561,700 tons, an increase of 21.98%. China above-scale enterprises are more carbon and graphite products, low concentration. By the end of 2011, China more than the size of graphite and carbon products business amounted to 871 graphite, sales revenue of the top ten of the total sales revenue accounted for only 13.46% of the entire industry. Trends and competition from carbon and graphite products in the world market, the future of carbon and graphite products industry will gradually focus to large groups, the concentration of carbon and graphite products industry will be further enhanced. Dense crystalline graphite dense crystalline graphite, also known as bulk graphite. Such crystalline graphite crystal clear visible. Particle diameter greater than 0.1 mm graphite company, focused on the specific surface area range 0.1-1m2 / g, crystal arrangement disorganized, dense block structure. This: Graphite is characterized by high grade, usually carbon content of 60 to 65%, sometimes up to 80 to 98%, but not as good as its plasticity and creamy fine flake graphite. _ _ Graphite graphite carbon industry is provided by the North Sea Dragon Sea Dragon Carbon Co., Ltd.
