In the present investigation hematite samples were reduced to magnetite by a mixture of H2 and H2O at 650, 700, and 750°C. These data have been analysed with the Johnson-Mehl equation and found to fit well in the nucleation and grain growth model. Activation energy values of the reaction were calculated by different methods and have been found to match closely.
