More Information
Summary:A metal titanium production apparatus includes: a reductor that subjects titanium tetrachloride to a reduction process in presence of bismuth and magnesium to obtain a liquid alloy containing titanium and the bismuth; a segregator that subjects the liquid alloy to a segregation process to obtain a precipitate; and a distillator that subjects the precipitate to a distillation process to obtain metal titanium, and the distillator sets an atmosphere so as to preferentially vaporize the bismuth attached to the precipitate and then sets the atmosphere so as to vaporize the bismuth forming the precipitate.
