Products Description
Graphitized Petroleum Coke (GPC) is a high-carbon material derived from petroleum coke through a high-temperature graphitization process. Its carbon structure resembles that of graphite crystals. This material is primarily used in the production of carbon products, electrode materials, refractory materials, and conductive fillers in the metallurgical industry.
Applications
Carbon Additives in the Metallurgical Industry
GPC is commonly used in steelmaking and iron casting processes as a carbon additive to adjust the carbon content in molten metal and improve the precision of material composition control.
Structural Improvement in the Foundry Industry
In the production of gray cast iron and ductile iron, GPC can improve the degree of graphitization and optimize the microstructure of the casting.
Refractory Raw Materials
GPC has excellent thermal stability and thermal conductivity, making it suitable for the manufacture of refractory materials such as high-temperature crucibles and furnace linings.
Electrodes and Conductive Fillers
GPC’s conductive properties make it suitable for use as a filler in electrodes, brushes, and conductive composite materials, and is widely used in the power equipment and electronics industries.
Battery Anode Materials
GPC, due to its graphitized structure, can be used as anode materials in lithium-ion batteries, improving electrical conductivity and energy density.

FAQ
Q: Can graphitized petroleum coke be used directly in steelmaking?
A: Yes, GPC can be added directly to the steelmaking process as a carbon additive to increase carbon content. It is suitable for various processes, including electric arc furnaces and blast furnaces.
Q: What is the difference between graphitized petroleum coke and ordinary petroleum coke?
A: GPC undergoes a high-temperature graphitization process, resulting in a more stable carbon structure and higher purity. Its conductivity and thermal stability are significantly superior to ordinary petroleum coke.
Q: How can I determine whether GPC is suitable for a specific casting process?
A: You can select a type based on process parameters such as the required carbon content, sulfur content, and absorption rate. This is recommended in conjunction with the melting method and final product requirements.
Q: Is graphitized petroleum coke suitable for long-term storage?
A: Yes, but it should be kept dry and ventilated to avoid moisture and contamination from impurities, which can affect its performance and carbon absorption rate.
Q: Are all GPC products suitable for battery anode materials?
A: No. GPC for batteries requires higher purity and a specific particle size. You should choose a product with a specification specifically designed for battery materials.
