Catalytic reduction of magnesia by carbon

Reduction kinetics of magnesia with carbon and transition metal was investigated by thermogravimetry from room temperature to 1973 K. Cu, Co and Ni accelerates the reduction rate. Fe accelerates the reduction rate and decreases the initial reaction temperature. The reaction with Fe addition takes place in three stages with activation energies in the second and third stage of 207 and 295 kJ mol−1.
