  • Metallic Iron an overview ScienceDirect Topics

    Metallic iron is mainly formed through gas–solid reduction, approximately 2/3 through indirect reduction and 1/3 through direct reduction. Carburization of iron can start at relatively low temperatures in contact with CO gas. Dissolution of carbon in solid iron or sponge lowers the melting point of iron significantly.
