Graphitized Petroleum Coke (GPC) is widely used as a high-quality carbon additive in steelmaking, foundries, cast iron production, ductile iron manufacturing and other metallurgical applications.
For buyers looking for a stable Graphitized Petroleum Coke supplier in China, key purchasing factors normally include fixed carbon, sulfur, nitrogen, ash, moisture, particle size and consistent batch quality.
As a supplier of graphite and carbon materials, Xingshi Graphite & Carbon provides GPC in different specifications and particle sizes for international industrial customers.
Graphitized Petroleum Coke, commonly known as GPC, is a carbon material produced from petroleum coke through high-temperature graphitization.
During the graphitization process, the material is treated at very high temperatures, which improves its carbon structure and reduces impurities.
Compared with conventional calcined petroleum coke, high-quality GPC generally offers:
High fixed carbon
Low sulfur
Low ash
Low moisture
Good carbon absorption
Stable chemical composition
Controlled particle size
These characteristics make GPC particularly suitable as a recarburizer or carbon raiser in metallurgical production.
Xingshi Graphite can supply different GPC grades according to customer applications and technical requirements.
Parameter | Typical Specification |
|---|---|
Fixed Carbon | 98.5%–99.5% Min |
Sulfur | 0.03%–0.50% Max |
Ash | 0.5%–1.0% Max |
Moisture | 0.5% Max |
Volatile Matter | Customized according to grade |
Particle Size | 0–1 mm, 1–3 mm, 1–5 mm, 2–5 mm or customized |
Note: Specifications can be adjusted according to application and customer requirements. Final parameters should be confirmed according to the agreed grade and COA.
GPC can be used as a carbon raiser in steel production to adjust the carbon content of molten steel.
Its high fixed carbon and relatively low impurity content make it suitable for applications where stable carbon addition is required.
Graphitized petroleum coke is commonly used in:
Grey iron casting
Ductile iron
Cast iron
Foundry production
Induction furnace melting
Particle size and sulfur level can be selected according to the customer's furnace conditions and production process.
GPC can also be used as a carbon additive in various metallurgical processes where high carbon content and controlled impurities are required.
For industrial buyers, selecting the correct GPC grade should not depend only on fixed carbon. Sulfur, nitrogen, ash, particle size and absorption performance should also be considered.
One common question from international buyers is the difference between GPC and CPC.
Property | GPC | CPC |
|---|---|---|
Full Name | Graphitized Petroleum Coke | Calcined Petroleum Coke |
Processing | High-temperature graphitization | Calcination |
Fixed Carbon | Generally higher | High |
Sulfur | Can be very low | Depends strongly on raw material |
Graphitization Degree | High | Lower |
Typical Use | Recarburizer, foundry, steelmaking | Carbon additive, anode and metallurgical applications |
Cost | Generally higher | Generally lower |
The best choice depends on the customer's production process rather than simply choosing the material with the highest carbon content.
For applications requiring low sulfur and high carbon, GPC is often preferred.
When sending an inquiry for Graphitized Petroleum Coke, providing the following information can help us recommend a more suitable grade:
Fixed Carbon (FC)
For example: 98.5%, 99% or 99.5% minimum.
Sulfur (S)
Low-sulfur GPC may be required for certain foundry and steel applications.
Particle Size
Common options include 0–1 mm, 1–3 mm, 1–5 mm and other customized sizes.
Application
Please indicate whether the material will be used for steelmaking, grey iron, ductile iron, foundry production or another metallurgical process.
Required Quantity
Trial orders and regular bulk requirements can be evaluated separately.
This information allows the supplier to recommend the appropriate GPC instead of quoting only according to carbon content.
Xingshi Graphite & Carbon supplies graphite and carbon materials to customers in the steel, foundry and metallurgical industries.
For GPC orders, we can support customers with:
Multiple GPC Grades
Different fixed carbon and sulfur levels can be selected according to the application.
Customized Particle Size
Particle size can be screened according to customer requirements.
Quality Inspection
Chemical composition and particle size can be checked before shipment.
COA Available
A Certificate of Analysis can be provided according to the supplied batch.
Sample Evaluation
Samples can be discussed for customers who need laboratory or production testing before bulk purchasing.
Export Packaging
Common options include 25 kg bags, jumbo bags and customized export packaging.
International Supply
We support trial orders as well as regular bulk purchasing requirements from overseas industrial customers.

GPC stands for Graphitized Petroleum Coke. It is a high-carbon material commonly used as a recarburizer or carbon raiser in steelmaking, foundry and cast iron production.
GPC undergoes a graphitization process, while CPC is produced through calcination. Their carbon structure, impurity levels, performance and cost can therefore differ.
Common sizes include 0–1 mm, 1–3 mm, 1–5 mm and 2–5 mm. Other particle size distributions can be discussed according to customer requirements.
Yes. Different sulfur levels can be supplied depending on the selected grade. Please specify your maximum sulfur requirement when sending an inquiry.
Yes. Chemical analysis can be provided according to the supplied material and agreed specifications.
Sample availability can be discussed according to the required specification, quantity and destination.
