The influences of oxide impurities or additives on the kinetics of the gaseous reduction of iron oxides have been systemically assessed, necessary quantitative analyses have been performed. The characteristics of the influences depend upon many experimental conditions involving the contents, of foreign oxides and their existing forms, and doping techniques, the initial chemical-composition and physical properties of the specimen , the reducing gas, reaction temperature as well as reaction fraction.
