Petroleum coke (green or calcined, **CPC**) is a carbonaceous material that works as a precursor to synthetic graphite and as an industrial recarburizer. It is not graphite until the graphitization process is complete.

## Applications

- Synthetic graphite manufacturing
- Recarburization
- Electrodes
- Refractories

Electrodes and finished graphite grades are derived materials or products, not the coke itself.
