Global Artificial (Synthetic) Graphite Market Research

The synonymous term often used for synthetic graphite is artificial graphite. Artificial Graphite or Synthetic Graphite refers to a graphitic carbon obtained from graphitizing of non-graphitic carbon. It is a residue material left behind after the petroleum coke has undergone refining and coking process.

Cast iron - Wikipedia

2019-5-4 · Cast iron is made from pig iron, which is the product of smelting iron ore in a blast furnace. Cast iron can be made directly from the molten pig iron or by re-melting pig iron, often along with substantial quantities of iron, steel, limestone, carbon (coke) and taking various steps to remove undesirable contaminants.
