By conventional production process of producing graphite carbon blocks using ordinary carbon production process can be made porous carbon and porous graphite block, except that the pore forming agent is added in the ingredients, a pore forming agent to generate pores volatilization or decomposition during firing and graphitization. The pore forming agent commonly used sodium chloride, sodium fluoride, sawdust, etc., to control the addition amount of a pore-forming agent and a pore forming agent is added in particle size, can substantially control porous carbon and porous graphite porosity and pore size. Industrial minerals will be divided into crystalline graphite (flake) graphite ore and stable crystalline (earthy) graphite ore into two categories. Crystalline flake graphite ores can be divided into two kinds of compact shape. Flake graphite ore to China crystal type, followed by the Aphanitic type graphite products, dense crystalline graphite-like Alexis de Puebla saw in Xinjiang, such as individual deposits, little industrial value. Stable crystalline graphite ore general was microcrystalline aggregates, crystal size less than 1μm graphite milk, only under the electron microscope to observe its crystalline form. Ore grayish black, steel gray graphite packing, usually glossy dark, with a dense block, earthy and layered, pp sheet structure. Process performance is better than implicit polycrystalline graphite flake graphite, industrial application is also smaller, ore grades are generally higher, but poor ore optional. Mineral composition of graphite-based, there are associated andalusite, water mica, sericite and minor pyrite, tourmaline, limonite, calcite. Grade is generally 60 to 80%, ash content of 15 to 22%, volatile content of 1 to 2%, a water content of 2 to 7%. Sea Dragon graphite packing _ _ Carbon graphite provided by Carbon Co., Ltd.
