The adiabatic temperature of ferric oxide aluminothermic system was analyzed based on the thermal dynamic theories. The results indicate that the boiling point of iron (i.e., 3 148.2 K) is an adiabatic temperature of different ferric oxide aluminothermic system (i.e., FeO/Al、Fe2O3/Al and Fe3O4/Al) under the standard condition. The gas phase conversion rate of iron product is different, i.e., 20.6% for FeO/Al, 21.3% for Fe2O3/Al and 2.0% for Fe3O4/Al. The adiabatic temperature and phase conversion rate decrease after adding diluent of ferroalloys into the thermits. According to the Fe2O3/Al thermit, the addition amount of ferroalloys (i.e., 0-1.35 mol and 3.75-5.10 mol) can control the phase conversion rate for gas phase of iron product and liquid phase of alumina product, correspondingly. The combustion wave can be self-propagated by preheating reactants when the adiabatic temperature is lower than 1 800 K after adding ferroalloys diluents. More addition amount of ferroalloys follows higher pre-heating temperature.
