2016/11/9 6 Aluminothermic Reaction 2Al+Fe2O3→Al2O3+2Fe+828kJ This process reacts sharply, and releases lots heats that the temperature of productions can be heated to 3000K. However, no gas is generated in this process, so the reaction can not work outside because of the lack of the medium which change the heat energy to the mechanic energy. Therefore, the reaction is not a explosion case. ★ ★
