Calcined Petroleum Coke (CPC) is a high-purity carbon material produced by heating green petroleum coke (a refinery byproduct) to roughly 1200–1400°C to remove volatiles and moisture. It is primarily used as an anode material in aluminum smelting, steel production, and for fabricating graphite electrodes, valued for its high density and conductivity.
