Chemical properties of elemental carbon at room temperature is relatively stable, insoluble in water, dilute acid, dilute base and an organic solvent; reaction with oxygen at high temperature combustion of different graphite manufacturers, raw [3] to carbon dioxide or carbon monoxide; halogen is fluorine, only with directly reacting elemental carbon; under heat, elemental carbon liable to acid oxidation; at high temperatures, the carbon can react with many metals to form metal carbides. Carbon having reducibility, at high temperature metal smelting. In graphite crystal, the carbon atoms in the same layer sp2 hybrid form a covalent bond, each carbon atom covalently linked to three with three other atoms. Six carbon atoms in the same plane as the formation of a regular six-shaped ring again and again, stretching into a lamellar structure, where the CC bond length are all 142pm, this is just part of the bond length range atomic crystals, so for the same layer, the It is the atomic crystal. Carbon atoms in the same plane is also a p-orbital of each remaining graphite, they overlap each other. Electronic relatively free of graphite products, equivalent to the free electrons in the metal, so that the graphite can be thermally and electrically conductive, which is characteristic of metal crystals. Therefore classified as a metal crystal. A major use is the production of graphite refractory, including the refractory bricks, crucibles, continuous casting powder, mold core, mold, detergents and high temperature materials. In recent years, the refractory industry in two important changes are MgO-C is widely used in steel-making furnace liner and aluminum carbon bricks used in the continuous casting. Graphite refractory and steel industry are closely linked, the world steel industry consumes about refractories. _ _ Graphite material graphite carbon industry is provided by the North Sea Dragon Sea Dragon Carbon Co., Ltd.
