The role and use of graphite

　　1, as refractory materials: graphite and its products with high temperature resistance, high strength properties, in the metallurgical industry is mainly used to manufacture graphite crucible.

　　2, as conductive material: used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, graphite gaskets, telephone parts, television picture tube coating, etc.

　　3, for wear-resistant lubrication materials: graphite is often used as a lubricant in the mechanical industry, graphite wear-resistant materials can be in 200~2000 ℃ temperature, at a high sliding speed, without lubricating oil work.

　　4, for casting, sand casting, molding and high temperature metallurgical materials: because of the small thermal expansion coefficient of graphite, and the ability to cold and hot changes, can be used as a glass mold.

　　5, used in atomic energy industry and national defense industry: graphite has good neutron moderator used in atomic reactors, uranium graphite reactor is currently used more of an atomic reactor.
