Wholesale Natural Granulated Graphite

Also known as: GPC (Graphitized Petroleum Coke), granulated graphite powder, graphite granular, carbon raiser, recarburizer.

High purity carbon additive produced from natural crystalline graphite. The powder, after being concentrated up to the desired carbon content, is transformed into pellets without adding any binder.

Features include: low ash and moisture content, basically free of hydrogen, nitrogen, oxygen, and sulfur, quick absorption, not scrap or by-product, and easy to apply. Since it is not hygroscopic, and very stable, it is perfect for long storage periods.

Available in big bags or pallets (25 kg small bags) in 1,000 kg (2,204.6 pounds, or 1 metric ton) lot sizes.

Minimum Order Quantity: 20 metric tons (20' Dry Cargo Container)

Please note: The top four grades in the tables below are more readily available than the bottom three.
