WIPO Patent Application WO/2019/235098
Kind Code:
A1
Abstract:
An apparatus for producing metal titanium is provided with a reduction device (1, 2, 3, 4, 5) for carrying out a reduction treatment of titanium tetrachloride (X2) in the presence of bismuth (X1) and magnesium (X3) to produce a liquid alloy (X4) composed of titanium and the above-mentioned bismuth, a segregation device (6) for carrying out a segregation treatment of the liquid alloy to produce deposits, and a distillation device (8) for carrying out a distillation treatment of the deposits to produce metal titanium, wherein, in the distillation device, the atmosphere is set in such a manner that the bismuth adhered to the deposits can be vaporized preferentially and is subsequently set in such a manner that the bismuth that forms the deposits can be vaporized.
