Structure evolution in the reduction process of FeO powder by hydrogen
工程科学学报, 2015 The isothermal hydrogen reduction kinetics of FeO powder at 773-1273 K was investigated by thermogravimetry. Above 873 K, there was a turning point in the kinetic curve, which indicated that the reduction mechanism changed.
