The Ti-Al alloy was synthesized using the aluminothermic reduction of TiO₂, with CaO and MgF₂ serving as flux components. Investigations were conducted to ascertain the effects of MgF₂ content on the alloy-slag separation, alloy microstructure, composition, phase constitution, overall alloy yield, and aluminothermic reduction of TiO₂. Results indicate that MgF₂ enhances the separation of the alloy from slag and promotes the formation of the TiAl phase within the alloy matrix. Nevertheless, an overabundance of MgF₂ reduces the interfacial tension between the Al reductant and the slag, leading to significant loss of Al. This adversely affects alloy-slag separation, escalates the incorporation of oxide inclusions in the alloy, and severely reduces the recovery rate of alloy. Concurrently, the alloy has a phase transition from TiAl to Ti₃Al. The optimum condition for alloy-slag separation and alloy integrity is realized at the MgF₂ content of 10wt%. Kinetic analysis at this flux ratio determines the activating energy for the Al-TiO₂-CaO-MgF₂ system, which is 409.729 kJ/mol, and the order of kinetics is n=0.38.
