High-Temperature (1700–1800°C) Electrochemical Preparation of Metallic Ti from Rutile: A Pathway of Step-by-Step Electrodeoxidization

Figure 3

CV curves obtained at 1750°C. (a) A TiO₂ slice (from oxidizing Ti foil at 1300°C for 1.5 hr) wrapped with Mo wire as working electrode (the inset of (a) shows the design of three electrodes (working electrode (A), reference electrode (B), and counter electrode (C)) before and after CV test at 1750°C); (b) only Mo foil as working electrode. The scan rate was 20 mV s⁻¹.
