Definition
A petroleum coke with good graphitizability, characterized by a combination of properties which differ significantly from those of metallurgical coke but do not reach the quality level of premium coke. These properties are: optical anisotropy, medium reversible thermal expansion and low ash content. Regular coke is mainly used for the production of synthetic carbon and graphite materials.
