Abstract

The present invention provides a method for preparing metallic titanium by electrolyzing molten salt with titanium circulation. The method mainly comprises reducing titanium tetrachloride (TiCl4) to at least one of titanium trichloride (TiCl3) and titanium dichloride (TiCl2) in chloride molten salt by metallic titanium (Ti), and electrolyzing the at least one of TiCl3 and TiCl2 in the chloride molten salt to form metallic titanium. According to the method for preparing metallic titanium of the present invention, TiCl2, and/or TiCl3 are prepared and electrolyzed continuously without changing the surrounding medium, thereby simplifying process flow, reducing power consumption, and realizing industrialization.

Claims (8)

1. A method for preparing metallic titanium by electrolyzing molten salt with titanium circulation, comprising:
i) reducing titanium tetrachloride (TiCl4) to at least one of titanium trichloride (TiCl3) and titanium dichloride (TiCl2) in chloride molten salt by metallic titanium (Ti);
and ii) electrolyzing the at least one of TiCI3 and TiCI2 in the chloride molten salt to form metallic titanium.
2. The method of claim 1, wherein the metallic titanium used in the step i) is a portion of metallic titanium obtained by electrolyzing at least one of TiCI3 and TiCI2.
3. The method of claim 1, wherein a mole ratio of the metallic titanium for reducing to TiCI4 is 1:1 to 1:3.
4. The method of claim 1, wherein the chloride molten salt is formed by melting two or more of LiCI, NaCI, KCI, MgCl2, CaCl2, SrCl2 and BaCl2.
5. The method of claim 4, wherein the chloride molten salt is at a temperature higher than the eutectic temperature of the chloride molten salt and lower than vaporization temperatures and decomposition temperatures of salts for forming the chloride molten salt.
6. The method of claim 5, wherein the chloride molten salt is at a temperature of 400~ to 850~.
7. The method of claim 1, wherein a small amount of sponge titanium, titanium powder or titanium scrap is added as a titanium source before electrolyzing so as to react with TiCl4, thereby obtaining TiCl2, TiCl3, or a mixture of TiCl2 and TiCl3 as electrolyte to induce electrolysis.
8. The method of claim 1, further comprising: collecting Cl2 liberated from an anode in the step ii).
