Preparation of TiAl Alloy by Magnesium Aluminum Synergistic Reduction of TiO2 in Molten Salt Medium

The traditional method of preparing TiAl alloy needs titanium and aluminum as raw materials for alloy preparation. The process of preparing pure metal is complex, the production process is too long, and high production causes energy consumption and serious pollution. In this study, a new method of preparing TiAl alloy by magnesium thermal reaction reduction of TiO2 in mixed molten salt was proposed. The experimental data and results show that the temperature of 750 °C is conducive to the reduction of TiO2. The mixed molten salt of KCl and MgCl2 is conducive to improving the mass transfer rate and promoting the reaction. The mixed molten salt of KCl and MgCl2 is conducive to improving the mass transfer rate and promoting the reaction. The titanium oxide is completely reduced. At the same time, the feasibility of this method is proved by experiments.
