Natural graphite comes from graphite deposits, but artificial graphite can also be produced from petroleum coke, pitch coke, and other raw materials through a series of processing steps. Graphite burns in oxygen to produce carbon dioxide and can be oxidized by strong oxidizing agents such as concentrated nitric acid and potassium permanganate. It can be used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in nuclear reactors. It is also used to manufacture crucibles, electrodes, brushes, dry cell batteries, graphite fibers, heat exchangers, coolers, electric arc furnaces, arc lamps, and pencil leads.
