Main raw material for artificial graphite is high quality calcined petroleum coke powder, add in asphalt as blinder, then add little other materials. Various raw material are well suppressed, and then graphitized in a non-oxidizing atmosphere at 2500~3000 degree. Ash, sulfur and gas content will be greatly reduced after the heat processing.
