Graphite Petroleum Coke (GPC) is a high-purity carbon material derived from petroleum refining. It is produced by heating green petroleum coke in a calcining process to remove volatile matter, resulting in a highly carbonaceous product with low sulfur and ash content. GPC is primarily used as a recarburizer in the steelmaking and foundry industries to increase the carbon content in molten metal, improving its quality and mechanical properties. It is also used in the production of electrodes for electric arc furnaces and in the manufacture of batteries, lubricants, and other industrial applications. GPC's high purity and consistency make it a valuable material in various industrial processes.
