Graphitized petroleum coke is a high-purity carbon material produced at a temperature of 2500-3500°C. It has the characteristics of high fixed carbon content, low sulfur, low ash, and low porosity.

Calcined petroleum coke is a method of calcining petroleum coke or green coke when using graphite electrodes for steelmaking or anode paste (melted electrodes) for aluminum or magnesium production.
