Electrodeposition of Ti in Molten Salt at High Temperature
Direct electrolysis of Ti-Fe alloy has been attempted in a CaF2-CaO-TiO2-FeO bath by the process using a direct-current electro-slag remelting unit. The electrolysis strongly depended on the electrolysis conditions,and Ti-Fe alloy was successfully obtained in the bath of a particular composition. The strong influence of the bath composition was also seen in the Ti and Ti-Al electrolysis in the previous,and suggested that the ca-thodic reaction of Ti was affected by the change in the bath composition. To clarify the influence of the bath composition,electrochemical measurement was carried out in a CaF2-MgF2-CaOTiO2 bath. The cathodic current due to Ti reduction was observed by cyclic voltammetry,and the change in the shape of cyclic voltammogram with the bath composition was found. This result indicated the change in the electrode reaction of Ti,and explained the results of the Ti electrolysis with a direct-current electro-slag remelting unit.
