Semi-Graphitized Petroleum Coke (Semi-GPC) is a carbon-rich material produced by calcining high-quality green petroleum coke at intermediate graphitization temperatures, typically between 1500°C and 2000°C. This partial graphitization process improves the crystalline structure and carbon content compared to regular calcined petroleum coke, while maintaining a more economical cost compared to fully graphitized products. Semi-GPC offers a balance between performance and price, making it a popular choice for various metallurgical applications.
Product Features
- Moderate Graphitization: Improved crystalline structure compared to regular calcined petroleum coke
- High Fixed Carbon: Typically 98.0% to 99.0%, providing efficient carburization
- Low Sulfur Content: Typically ≤ 0.05%, suitable for clean steel and ductile iron applications
- Lower Ash and Volatile Matter: Helps reduce impurities and slag generation
- Good Carbon Recovery Rate: Enhances melt quality and reduces material consumption
- Better Electrical Conductivity than calcined petroleum coke, though lower than full GPC
