Graphitized Petroleum Coke GPC is made from high quality petroleum coke under a temperature of 2500- 3500℃. It is widely used as the best kind of recarburizer for producing high quality steel,special steel or other related metallurgical industries,Advantage with it´s high fixed carbon content,low sulfur content and high absorb rate.
As a high purity carbon material, it has characteristics of high fixed carbon content, low sulfur, low ash, low porosity etc. It can be used as carbon to produce high quality steel, cast iron and alloy. It can also be used in plastic and rubber as an additive.
The characteristics of high-quality carburetors include:
1. Moderate particle size, high porosity, and fast absorption rate.
2. The chemical composition is pure, with high carbon, low sulfur, minimal harmful components, and high absorption rate.
3. The graphite crystal structure of the product is good, improving the nucleation ability of the original iron liquid. Increase the number of graphite balls in ductile iron during incubation, and add graphite crystal nuclei in electric furnace molten iron. Refine and evenly distribute graphite in castings.
4. Excellent performance and stability.
Carburizing agents are indispensable additives in the steelmaking industry. Different types of steel require different specifications of carburizing agents.
Application :
It can be used as carbon raiser (Recarburizer) to produce high quality steel, cast iron and alloy. It can also be used in plastic and rubber as an additive.

FAQ – Graphitized Petroleum Coke (GPC)
1. What is Graphitized Petroleum Coke (GPC)?
Graphitized Petroleum Coke (GPC) is a high-carbon material produced from petroleum coke through high-temperature graphitization. It features high fixed carbon, low sulfur and low impurities, and is widely used as a carbon raiser or recarburizer in metallurgical applications.
2. What is GPC used for?
GPC is mainly used as a carbon raiser and carbon additive in steelmaking, foundry, casting, grey iron and ductile iron production. It helps adjust the carbon content of molten metal during the melting process.
3. What is the difference between GPC and CPC?
GPC (Graphitized Petroleum Coke) undergoes high-temperature graphitization, while CPC (Calcined Petroleum Coke) is produced through calcination. GPC generally has a higher degree of graphitization and is available in high-carbon, low-sulfur grades for steelmaking and foundry applications.
4. What particle sizes of GPC are available?
Common GPC particle sizes include 0–1 mm, 1–3 mm, 1–5 mm and other customized sizes. Particle size can be selected according to the customer's furnace type, application and production requirements.
5. Can you supply low sulfur GPC?
Yes. We can supply low sulfur Graphitized Petroleum Coke for applications requiring controlled sulfur content. Our available grades include GPC with fixed carbon ≥98.5% and sulfur ≤0.05%, subject to the final agreed specification.
6. Can you provide a COA before shipment?
Yes. A Certificate of Analysis (COA) can be provided for the supplied GPC batch. Key parameters such as fixed carbon, sulfur, ash, moisture and particle size can be inspected according to the agreed specification.
7. Can I get a sample before bulk purchasing?
Yes. Samples can be arranged for customers who need laboratory testing or production evaluation before placing a bulk order. Please provide your required GPC specification, particle size, sample quantity and delivery destination.
8. How can I get a quotation for Graphitized Petroleum Coke?
Please send us your required fixed carbon, sulfur content, particle size, application, quantity and destination port. Xingshi Graphite can recommend a suitable GPC grade and provide a quotation based on your purchasing requirements.
