The deoxidizing process of the preparation FeTi alloy by electrolysis ilmenite concentrate in molten salt

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.
