High-Temperature (1700–1800°C) Electrochemical Preparation of Metallic Ti from Rutile: A Pathway of Step-by-Step Electrodeoxidization
Figure 4
Plots of electrochemical reduction potentials of Ti oxides against temperatures: (a) TiO + 2e− = Ti + O2−; (b) Ti2O3 + 2e− = 2TiO + O2−; (c) 2Ti3O5 + 2e−= 3Ti2O3 + O2−; (d) 3Ti4O7 + 2e− = 4Ti3O5 + O2−; (e) 4TiO2 + 2e− = Ti4O7 + O2−. The vertical dashed line indicates the electrochemical reduction potentials of different Ti oxides at 1750°C.
