As soft magnetic alloy, Si steel has been brought to the attention of the people. When the content of Si is about 6.5%, the magnetic induction intensity is highest, and the wastage of the iron is lowest, with good magnetic energy. Due to the brittleness and poor process-ability of the 6.5% Si silicon, the traditional production process is very difficult to be used for the production. With traditional production process, the content of Si in silicon steel is commonly 0.1% ~ 4.0%, which makes the property of the silicon steel limited. Use molten salt electro-position method to product silicon steel on the basis of silicon steel surface, to lay the foundation for producing 6.5% Si silicon steel. The influence of the process parameters of molten salt electro-position method to the deposit surface morphology and the silicon content distribution from surface to inside shows that along with the increase of the electro-position time, the size of sediment particle on the deposit surface gradually increases. The sedimentary thickness is proportional to the electro-deposition time.

The electrochemical reduction mechanism of Mn in LiMn2O4 in molten salt was studied. The results show that in the NaCl-CaCl2 molten salt, the process of reducing from Mn (IV) to manganese is: Mn (IV)→Mn (III)→Mn (II)→Mn. LiMn2O4 reacts with molten salt to form CaMn2O4 after being placed in molten salt for 1 h. The reaction of reducing CaMn2O4 to Mn is divided into two steps: Mn (III)→Mn (II)→Mn. The results of constant voltage deoxidation experiments under different conditions show that the intermediate products of LiMn2O4 reduction to Mn are CaMn2O4, MnO, and (MnO)x(CaO)(1−x). As the reaction progresses, x gradually decreases, and finally the Mn element is completely reduced under the conditions of 3 V for 9 h. The CaO in the product can be removed by washing the sample with deionized water at 0 °C.
