The influence of the heat of reaction during the aluminothermic process for the production of ferrotita nium was investigated. The effect of the variation of the heat of reaction on FeTi and Ti recovery and the topographical analysis of slag produced showed that FeTi and Ti recovery increased and AI content in the alloy decreased with the increase of the absolute value of △Hwhen |△H|<2584.24K.J/kg; however, when |△H| >2584.24K·J/kg, FeTi and Ti recovery decreased with an increase of the absolute value of △H. Therefore, the heat of reaction in the aluminothermic process of ilmenite should be strictly controlled to -2584.24K·J/kg.
