Abstract

A method for producing an aluminum material, including: providing an electrolytic cell in which an anode electrode containing 0.01 to 30% by mass Si and Al and a cathode electrode are immersed in an electrolytic solution and depositing aluminum on the cathode electrode by energizing the anode electrode and the cathode electrode in the electrolytic solution.

First claim

What is claimed is:

1 . A method for producing an aluminum material, comprising:
providing an electrolytic cell in which an anode electrode containing 0.01 to 30% by mass Si and Al and a cathode electrode are immersed in an electrolytic solution and depositing aluminum on the cathode electrode by energizing the anode electrode and the cathode electrode in the electrolytic solution.

2 . The method for producing an aluminum material according to claim 1 , wherein an area ratio of Si to a surface of the anode electrode is 90% or less in depositing aluminum on the cathode electrode.

3 . The method for producing an aluminum material according to claim 1 , wherein the electrolytic solution comprises a molten salt containing an alkylimidazolium halide and an aluminum halide.

4 . The method for producing an aluminum material according to claim 1 , wherein
the anode electrode comprises an aluminum alloy containing Si: 0.01 to 30% by mass, Fe: 1.8% by mass or less, Cu: 5.0% by mass or less, Mg: 10.5% by mass or less, Mn: 1.5% by mass or less, Zn: 3.0% by mass or less, Ni: 0.55% by mass or less, Ti: 0.3% by mass or less, Pb: 0.35% by mass or less, Sn: 0.3% by mass or less, and Cr: 0.15% by mass or less, with the balance being Al and inevitable impurities, and the anode electrode is platy or an aggregate of particles having an average particle size of 1 to 100 mm.

5 . The method for producing an aluminum material according to claim 1 , wherein
the anode electrode comprises an aluminum alloy containing Si: 0.01 to 30% by mass, Fe: 1.8% by mass or less, Cu: 5.0% by mass or less, Mg: 10.5% by mass or less, and Mn: 1.5% by mass or less, with the balance being Al and inevitable impurities, and the anode electrode is platy or an aggregate of particles having an average particle size of 1 to 100 mm.

6 . An apparatus for producing an aluminum material, comprising:
an electrolytic cell storing an electrolytic solution; an anode electrode immersed in the electrolytic cell and containing 0.01 to 30% by mass Si and Al; a cathode electrode immersed in the electrolytic cell; and a voltage-applying unit configured to enable application of a voltage between the anode electrode and the cathode electrode.
