Abstract
Official abstract text for this publication.
A method for producing a titanium foil according to the present invention includes an electrodeposition step of performing electrolysis with electrodes including an anode and a cathode using a molten salt bath comprising titanium ions and having at least one molten chloride to deposit metal titanium onto an electrolytic surface of the cathode, wherein the electrodeposition step includes maintaining a ratio of a molar concentration of titanium ions to the total molar concentration of metal ions in the molten salt bath at 7% or more, and maintaining a temperature of the molten salt bath at 510° C. or less, and conducting a current to the electrodes under conditions where a continuous stop time of current conduction is less than 1.0 second, a current density is 0.10 A/cm 2 or more and 1.0 A/cm 2 or less, and a time for electrodepositing the metal titanium onto the electrolytic surface of the cathode is 120 minutes or less.

1 . A method for producing a titanium foil, the method comprising: an electrodeposition step of performing electrolysis with electrodes including an anode and a cathode using a molten salt bath comprising titanium ions and having at least one molten chloride to deposit metal titanium onto an electrolytic surface of the cathode, wherein the electrodeposition step comprises maintaining a ratio of a molar concentration of titanium ions to a total molar concentration of metal ions in the molten salt bath at 7% or more, and maintaining a temperature of the molten salt bath at 510° C. or less, and conducting a current to the electrodes under conditions where a continuous stop time of current conduction is less than 1.0 second, a current density is 0.10 A/cm 2 or more and 1.0 A/cm 2 or less, and a time for electrodepositing the metal titanium onto the electrolytic surface of the cathode is 120 minutes or less. 2 . The method for producing a titanium foil according to claim 1 , wherein the anode comprises Ti and the anode is consumed in the electrodeposition step. 3 . The method for producing a titanium foil according to claim 1 , wherein the chloride comprises titanium dichloride and/or titanium trichloride. 4 . The method for producing a titanium foil according to claim 1 , wherein, in the electrodeposition step, the ratio of the molar concentration of titanium ions to the total molar concentration of metal ions in the molten salt bath is maintained at 10% or more. 5 . The method for producing a titanium foil according to claim 1 , wherein, in the electrodeposition step, the temperature of the molten salt bath is maintained at 500° C. or less. 6 . The method for producing a titanium foil according to claim 1 , wherein, in the electrodeposition step, the current density is 0.20 A/cm 2 or more and 0.50 A/cm 2 or less. 7 . The method for producing a titanium foil according to claim 1 , wherein the molten salt bath does not comprise fluoride ions. 8 . The method for producing a titanium foil according to claim 1 , wherein a surface of the anode and an opposing surface of the cathode have similar shapes to each other. 9 . The method for producing a titanium foil according to claim 1 , wherein a distance between the electrodes of the anode and the cathode is 0.5 cm or more and 10.0 cm or less.
