Graphite is an allotrope of carbon, gray black, opaque solid, chemical stability, corrosion resistance, with acid, alkali and other agents are not easy to react. Natural graphite from graphite deposits, can also be petroleum coke, asphalt coke and other raw materials, through a series of processes to make artificial graphite. Graphite is burned in oxygen to produce carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. It can be used as an antiwear agent, lubricant, high purity graphite is used as a neutron moderator in atomic reactors, and can also be used in the manufacture of crucible, electrode, brush, dry battery, graphite fiber, heat exchanger, cooler, electric arc furnace, arc lamp, pencil lead and so on.
