以攀枝花地区的钛精矿为原料通过CaCl2熔盐电解工艺直接制备FeTi合金。主要通过不同时间间断实验对电解过程进行跟踪,结果表明以钛精矿为原料电解制备FeTi合金的过程中首先得到金属铁和钙钛矿,然后是钙钛矿电解得到钛的低价氧化物,最后是钛的低价氧化物电解得到钛和形成FeTi合金,通过阴极失重实验验证了分段反应的结论。最后对钙钛矿的形成机理进行了实验研究,得到CaTiO3形成有两个途径：（1）熔盐参与反应,并且是主要成因;（2）熔盐CaCl2水解得到CaTiO3。
The FeTi alloy can be prepared directly by electrolysis in CaCl2 molten salt.The raw material is ilmenite concentrate from Panzhihua area.The main purpose of the paper is tracking deoxideation process through interrupted experiments at different time.The results show that the iron and perovskite are first obtained during the process of preparing FeTi alloy through electrolysis ilmenite concentrate in CaCl2 molten salt.Then the titanium suboxide can be obtained by electrolysis the perovskite.Finally,FeTi alloy can be obtained by electrolysis the titanium suboxide.The weight loss experiments of the cathode verified the conclusion of the previous studies.The final part of the paper studies the formation mechanism of perovskite through experiments.There have two ways,the main reason is reaction of salt,and another reason attributed to the hydrolysis of CaCl2 molten salt.
