The results obtained were as follows. The rate of reduction of hematite to magnetite was not affected by the presence of water vapor, as expected from thermodynamic calculations. The rates of later steps of reduction were decreased considerably as the ratio of partial pressures of steam to hydrogen was increased. Particularly, the rate of the last step, the production of metallic iron, is strongly affected.}, pages = {185--192}, title = {The effect of water vapor on the rate of reduction of iron ore by hydrogen}, volume = {17}, year = {1966} }
