Carbon graphite, the North Sea Dragon Carbon and graphite by Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd. Weifang Sea Dragon (www.longmentanye.com) is specialized in the "graphite" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Chin. Aphanitic graphite Aphanitic Aphanitic graphite graphite, also known as microcrystalline graphite or earthy graphite, graphite crystal diameter which is generally less than 1 micron graphite, the specific surface area in the range of focus 1-5m2 / g, microcrystalline graphite aggregates, only under an electron microscope to see the crystal form. Such graphite surface is characterized by earthy graphite milk, lack luster carbon graphite, slightly lower than the flake graphite lubrication. Higher grade. Usually 60 to 85%. Few as high as 90%. More generally used in the foundry industry. The main hidden in Chenzhou, Hunan Lu Tong. With the increase of this graphite purification technology. Amorphous graphite is widely applied. Graphite products environmental health, no radioactive contamination, high temperature. Carbon to go through at 2000-3300 degree heat at least a dozen environmental circadian graphitization process in order to become graphite, therefore, graphite release of hazardous substances already exhausted, at least within 2000 degrees is stable.
