Graphite Petroleum Coke is a high carbon, high purity material formed from petroleum coke that has been subjected to a high-temperature graphitization process (temperatures typically reaching 2500°C or more). The graphitization process rearranges the carbon atoms in the petroleum coke into a graphite-like crystal structure, thereby improving its electrical conductivity, heat resistance and chemical stability. Graphite petroleum coke has excellent properties and is widely used in metallurgy, batteries, carbon products and other high-end applications.
graphite petroleum coke characteristics
1. High Carbon Content: The fixed carbon content of graphite petroleum coke is usually above 98%-99%.
2. Low Sulfur and Low Ash: After graphitization, the sulfur content is extremely low (usually less than 0.05%) and the ash content is significantly reduced.
3. Good electrical conductivity: graphite structure significantly improves its electrical conductivity, suitable for high current environment.
4. High Temperature Stability: Graphitization gives it excellent high temperature resistance, and it is not easy to decompose or oxidize under extreme temperatures.
5. Good Mechanical Strength: Structural stability, high resistance to compression and abrasion.
6. Chemical inertness: acid and alkali corrosion resistance, suitable for various chemical environments.
