[0002] Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties and corrosion resistance. It does not easily react with acids, alkalis and other agents. It can be used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in atomic reactors. It can also be used to make crucibles, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, pencil refills, etc. The different sizes of graphite tailings have different uses and need to be screened.
