The Direct Reduction of Iron

If iron oxide is reduced directly to metal using hydrogen, a dense iron phase forms on the surface of the pellet, making it difficult for reduction to proceed However, if the H 2 /H 2 O ratio is chosen to make w├╝stite instead, this layer is porous and reduction to metal can occur rapidly afterward [ 51 ]...
