| Abstract: | A new process is developed to synthesize the precious alloy directly from the oxide mixtures. This process consists of calciothermic reduction in molten CaCl2 and electrochemical reaction for the recovery of Ca from CaO in the same bath. The molten CaCl2 can dissolve Ca and CaO for complete reaction. The oxide mixture consisting of TiO2, Al2O3, and V2O5 was prepared. Either a simple mixture of oxides or its calcined sample was reduced in the molten CaCl2+CaO. The obtained metallic powder was identified as α-Ti single phase and it contained only about 3000 mass ppm oxygen. Although its metallic composition was close to Ti-6Al-4V, this reduced powder had a broad compositional distribution. This inhomogeneous distribution was improved by the subsequent sintering in argon. |
