In this study, the electrochemical deoxidation of Ti scrap metal was performed at 800, 850, 900, and 950 °C using graphite and Pt as the electrodes and molten MgCl2 as the electrolyte. These temperatures were selected to investigate how the efficacy of deoxidation was affected by the Ti crystallographic structure, as the body-centered cubic β-Ti phase occurs above 882 °C. The results revealed that temperature significantly influences the oxygen diffusion rate and kinetics of deoxidation reactions. A corresponding kinetic model was developed to gain insights into the deoxidation mechanism. The measured oxygen content after deoxidation at 800, 850, 900, and 950 °C was 2100, 1900, 1500, and 3494 ppm, respectively. Furthermore, the effect of MgO activity on the Ti deoxidation rate was experimentally proven to be a function of temperature. These findings indicate that the best deoxidation performance is achieved at 900 °C, compared to the other tested temperatures. [ABSTRACT FROM AUTHOR]
