Sponge iron generally consisted of Fe3O4 under high temperature conditions in the flow of hydrogen or carbon monoxide gas reduction and generation, main components for the loose structure of elemental iron. Due to the direct iron powder itself has powder, coupled with the micro structure is very loose, so the surface actively.
