Abstract
This study investigates the deoxidation process of low-grade titanium scrap through molten salt electrolysis induced by overpotential. The research focuses on understanding the efficiency and mechanisms involved in the deoxidation of titanium scrap, utilizing induced overpotential as a key parameter. The analysis includes a detailed examination of the molten salt deoxidation process, with emphasis on electrochemical reactions and overall performance. The findings contribute valuable insights into the application of induced overpotential in enhancing the deoxidation of low-grade titanium scrap through molten salt electrolysis. This research contributes to the optimization of titanium recycling processes, with potential implications for sustainable and resource-efficient metallurgical practices. The induction of overvoltage phenomena was intentionally introduced to achieve an oxygen separation efficiency beyond thermodynamic limits. Furthermore, the correlation between electrochemical factors, formation electrode potential, and oxygen removal efficiency was elucidated. The initial titanium scraps, characterized by an oxygen concentration of 5500 ppm and a purity of 98.2 %, underwent a significant enhancement in characteristics, reaching 1850 ppm of oxygen concentration and 98.97 % purity after the first electrolysis process. In summary, this study presents a comprehensive approach to the separation and purification of titanium from low-grade scraps, by molten salt electrolysis.
期刊介绍:
Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
