1. Chemical component: High carbon, low sulfur and nitrogen, few impurities
2. Physical form: Clean, porous, quick and efficient for absorption.
3. Microcosmically:Better crystal quality, better property of the cast iron.
4. Property: teady in performance, reliable in raising carbon content, no slag returned.

To raise carbon in electric induction furnaces, in cupola furnaces, for duplex melting process, for spraying carbon powder into liquid iron.
