摘要

本研究探讨了通过过电位诱导熔盐电解低级钛废料的脱氧过程。研究重点是利用诱导过电位作为关键参数,了解钛废料脱氧过程的效率和机理。分析包括对熔盐脱氧过程的详细检查,重点是电化学反应和整体性能。研究结果为诱导过电位在通过熔盐电解增强低级钛废料脱氧过程中的应用提供了宝贵的见解。这项研究有助于优化钛回收工艺,对可持续和资源节约型冶金实践具有潜在影响。为了实现超出热力学极限的氧气分离效率,特意引入了过电压现象。此外,还阐明了电化学因素、形成电极电位和除氧效率之间的相关性。初始钛渣的氧浓度为 5500 ppm,纯度为 98.2%,经过第一次电解过程后,钛渣的特性显著增强,氧浓度达到 1850 ppm,纯度达到 98.97%。总之,本研究提出了一种通过熔盐电解从低级废料中分离和提纯钛的综合方法。

Electrochemical behavior of deoxidation titanium scrap process by induced overpotential molten salt electrolyte

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.
