Abstract

Reduction reaction can happen among Al, V2O5 and TiO2 powders. Al can deoxidize metal V and Ti from the metal oxides. The electric igniter can be used to trigger the reduction. The reaction between Al and V2O5 is very intense and release large amounts of heat, but the heat which is needed to initiate the reaction between Al and TiO2 is not enough. These two reactions have been initiated first and V-Al and Ti-Al alloys can be obtained with a higher metal recovery percent. Through adjusting the ratio of Al, V2O5 and TiO2 powders, the system which combines these two reactions can ensured enough heat to react. KClO3 is added to the system, as the ignition agent, in order to make the reaction much complete. Finally, Ti-Al-V alloys can be obtained and need remelt to adjust the constituents.
