Graphitized Petroleum Coke (GPC)

CAS No.7782-42-5

Graphitic petroleum coke is mainly used as a carbon additive, reducing agent, and cathode/anode raw material in industry, and is widely used in steelmaking, casting, aluminum industry, and battery material manufacturing. It participates in reactions or melting in the form of basic chemical elements (carbon elements) in these production processes, belonging to the typical category of upstream chemical engineering and basic materials.
