The behavior of impurities in electrorefining of Ti by NaCl-KCl-TiClx molten salts and the production process of its molten salts have been studied. As a result, purification of salts, materials for the apparatus and the quality of anode Ti were important for the production of high purity Ti. By using purified molten salts and the apparatus constructed of Ni, impurities of the Ti deposit, such as Fe, Ni, could be lowered to about 0.01 ppm. The contents of Al and Cr of this Ti were about 0.1 ppm. Volatile impurities were removed from the Ti obtained in this process by electron beam melting and Ti ingots with grades in excess of 6N (except for gas elements) were obtained.
