      4 with Ca.
      SOLUTION: In a method for producing Ti or a Ti alloy through a reduction step of reacting a metallic chloride containing TiCl
      4 with Ca in a salt bath containing Ca to form Ti or the Ti alloy in the salt bath, and an electrolysis step of producing Ca by electrolyzing a salt extracted from the salt bath used in the reduction step. This production method comprises: collecting a solid substance 5 containing Ca and the salt in the electrolysis step; and transferring the solid substance to the salt bath used in the reduction step. It is possible to collect the solid substance by drawing up the solid substance 5 while depositing and solidifying it on the surface of a cathode 4 for instance.

    • PROBLEM TO BE SOLVED: To provide a method for producing titanium and a titanium alloy, by electrolyzing metallic oxide containing titanium oxide in a molten salt so as to reduce the titanium oxide.
      SOLUTION: This production method comprises the steps of: charging a continuum made of a metallic oxide containing titanium oxide or further mixed with metallic titanium, into the molten salt including calcium chloride; passing an electric current between the continuum of a cathode and an anode immersed in the molten salt, to reduce the metallic oxide containing titanium oxide included in the continuum; and extracting the reduced continuum from the molten salt. When the production method employs the continuum comprising a conductor substrate and the metallic oxide containing titanium oxide deposited on the surface, it provides a layer of titanium or the titanium alloy on the surface of the substrate, which has been reduced from the metallic oxide containing titanium oxide.
