采用四氯化钛（TiCl 4）气体作为反应物，通过在钛阴极上原位生成TiCl 2的电解获得钛。该方法包括将TiCl 4气体连续供给到浸没在熔融盐（NaCl-KCl）中的钛阴极上反应，由此通过歧化反应原位形成二氯化钛（TiCl 2）。同时，在熔融盐介质中原位形成的TiCl 2已经反应成氯气和钛，最后通过电解沉积在钛阴极上。在TiCl 2原位形成速率和恒电流电沉积速率方面研究了该创新工艺的反应动力学，其中，特别地，研究了操作变量如TiCl 4分压和流速以及温度和施加的电流电势的影响。
An innovative process using titanium tetrachloride (TiCl4) gas as reactant has shown successfully to obtain titanium through electro-winning of TiCl2 formed in-situ on titanium cathode. The process involves a continuous feed of TiCl4 gas reacting onto a titanium cathode immersed in a molten salt (NaCl-KCl), whereby in-situ formation of titanium dichloride (TiCl2) through a disproportion reaction. Simultaneously, the TiCl2, thus in-situ formed in the molten salt media, has been reacted into chlorine gas and titanium, the latest electrodeposited on the titanium cathode by electrowinning. The reaction kinetic of this innovative process was investigated in terms of TiCl2 in-situ formation rate and galvanostatic electrodeposition rate, where, in particular, the effect of operating variables such as TiCl4 partial pressure and flow rate, as well as temperature and galvanic potential applied was investigated.
