| 摘 要： | 钛作为一种重要的金属越来越为人们所重视,因此降低钛的生产成本势在必行.TiO2的直接电化学还原法是一种低能耗、无污染的绿色生产新工艺.目前国内外研究较多的制取钛的新工艺有:FFC剑桥法、EMR法和OS法等.通过TiO2电解实验得到了Ti,并进行了相关的热力学分析与计算,证明TiO2的还原是逐级进行的;同时分析了实验的主要影响因素及其控制方法,为进一步研究TiO2电解制取Ti的机理与工艺提供了一定的依据.

| Abstract: | Titanium is more emphasized as a kind of important metal, so it is essential to reduce the cost of ti tanium production. Direct electrochemical reduction of TiO2 is a new green process with low energy consumption and non-pollution. At present, the processes of titanium preparation in and abroad include FFC, EMR, OS and so on. Through the experiment of TiO2 electrolysis, titanium is gained. At the same time, some related thermodynamics analysis and accounts are made, and the reduction of TiO2 is conducted by several steps is proved. The primary influencing factors and the controlling means are also analyzed. Some theoretical evidences are provided for studying further the mechanism and process of the experiment. |
