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.

What Is Graphitized Petroleum Coke?

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.

Typical GPC Specifications

Xingshi Graphite can supply different GPC grades according to customer applications and technical requirements.

Note: Specifications can be adjusted according to application and customer requirements. Final parameters should be confirmed according to the agreed grade and COA.

Main Applications of Graphitized Petroleum Coke

1. Steelmaking

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.

2. Foundry and Cast Iron

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.

3. Metallurgical Carbon Additive

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.

GPC vs. Calcined Petroleum Coke (CPC)

One common question from international buyers is the difference between GPC and CPC.

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.

How to Choose the Right GPC Grade

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.

FAQ – Graphitized Petroleum Coke

What is GPC?

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.

What is the difference between GPC and CPC?

GPC undergoes a graphitization process, while CPC is produced through calcination. Their carbon structure, impurity levels, performance and cost can therefore differ.

What GPC particle sizes are available?

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.

Can you supply low-sulfur GPC?

Yes. Different sulfur levels can be supplied depending on the selected grade. Please specify your maximum sulfur requirement when sending an inquiry.

Can you provide a COA?

Yes. Chemical analysis can be provided according to the supplied material and agreed specifications.

Can I get a GPC sample before ordering?

Sample availability can be discussed according to the required specification, quantity and destination.
