Petroleum Coke GPC and CPC High Fixed Carbon Carbon Additive
Premium carbon materials for steelmaking, foundry, and aluminum industry applications with high fixed carbon content and controlled specifications.
Petroleum Coke Carbon Material Overview
Petroleum Coke is a carbon-rich material widely used in metallurgical and industrial carbon applications. According to different processing methods, petroleum coke is mainly classified into Calcined Petroleum Coke (CPC) and Graphitized Petroleum Coke (GPC).
Through calcination or graphitization treatment, petroleum coke obtains improved carbon purity, reduced volatile matter, controlled sulfur content, and enhanced carbon performance.
Primary Applications
- Steelmaking carbon addition
- Foundry recarburization
- Aluminum carbon anode production
- Graphite electrode manufacturing
- Metallurgical carbon applications
