Technologies for removing oxygen (O) directly from titanium (Ti) scrap are highly important from an industrial view point. In our previous study, a thermochemical deoxidation method of Ti using Y metal in YCl<sub>3</sub> (<i>l</i>) was developed. We demonstrated that Ti with an extremely low O concentration (30–60 ppm O) can be reliably obtained utilizing the Y/YOCl/YCl<sub>3</sub> equilibrium. To further decrease O contamination in Ti, in this study, an electrochemical deoxidation method was designed and investigated in molten salts containing YCl<sub>3</sub> (<i>l</i>). The set-up consists of a Ti anode and a graphite cathode. This method can be applied for semi-continuous deoxidation of Ti and has a high tolerance for O contamination during the process. The establishment of this method is expected to promote the efficient recycling of Ti scrap in the future.
