Abstract The electrical transport properties of molten TiO 2 –SiO –Al O 3 –MgO–CaO slags were determined as a function temperature and oxygen partial pressure. To avoid the corrosion crucible materials by this slag at ultra high temperatures, pendant droplet technique was used inside modified floating zone furnace. Electronic ionic transference numbers estimated using stepped-potential chronoamperometry experiments to quantify contribution electronic/ionic conductivity total electric...
The reduction process during the electrochemical production of titanium via electrolysis molten TiO 2 –SiO –Al O 3 –MgO–CaO slags has been investigated. A laboratory scale, electrolytic cell was designed to study effect concentration at ultra-high temperatures. Galvanostatic and potentiostatic experiments were performed results consistent with thermodynamic predictions using FactSage. We demonstrate direct Si-Ti alloys from oxide mixture. Si Ti ions melt on a molybdenum electrode is complex...
Recently, the electrochemical recovery of metals from molten TiO 2 - SiO Al O 3 MgO CaO slag has been proven feasible. The use largest by-product ironmaking process as an electrolyte potential producing titanium metal in a more sustainable and environmentally friendly manner than current Kroll process. However, extensive understanding behaviour this complex oxide system its state is paramount for design industrial electrolytic cells. In work, we present results electrolysis experiments...
