石墨是自然元素碳的结晶矿物,是一种特殊的非金属材料。石墨的晶形为板状或片状,解理极完全,硬度1—2,黑色,不透明,不发光,有金属光泽,导电性良好,可塑耐腐,不怕高温,化学性稳定,手摸有滑感,染手。石墨是在特殊的地质环境下形成的。石墨的用途极广,主要用于冶金、铸造、机械、电器、化学、轻工、原子能及国防等。随着国民经济的飞速发展,其需要量将越来越多。我国的石墨矿产资源丰富,在
Graphite is a natural mineral element of the crystalline minerals, is a special kind of non-metallic materials. Graphite crystal plate or sheet, cleavage very complete, hardness 1-2, black, opaque, non-luminous, metallic luster, good electrical conductivity, plastic corrosion, not afraid of high temperature, chemical stability, Sense, dye hands. Graphite is formed in a special geological environment. The use of graphite is very wide, mainly for metallurgy, casting, machinery, electrical, chemical, light industry, atomic energy and national defense. With the rapid development of the national economy, its demand will be more and more. China’s graphite mineral resources are abundant
