    • PROBLEM TO BE SOLVED: To provide a method for producing an aluminum film, capable of continuously producing a large amount of aluminum films having a mirror surface and excellent surface smoothness.SOLUTION: In a method for producing an aluminum film, aluminum is electro-deposited on a substrate surface in an electrolyte. The electrolyte comprises, as components thereof: (A) aluminum halide; (B) one or more compounds selected from the group consisting of alkyl pyridinium halide, alkyl imidazolium halide and an urea compound; and (C) 1,10-phenanthroline monohydrate. A mixture ratio of the component (A) and the component (B) is within a range of 1:1-3:1 in molar ratio. The concentration of the 1,10-phenanthroline monohydrate in the electrolyte is controlled to be within a range of 0.05 g/L-7.5 g/L.
    • 要解决的问题:提供一种能够连续生产具有镜面的大量铝膜和优异的表面光滑度的铝膜的制造方法。解决方案:在铝膜的制造方法中,电沉积铝 在电解质中的基底表面上。 电解质作为其成分包含:(A)卤化铝; (B)一种或多种选自烷基吡啶鎓卤化物,烷基咪唑鎓卤化物和脲化合物的化合物; 和(C)1,10-菲咯啉一水合物。 组分(A)和组分(B)的混合比在摩尔比为1:1-3:1的范围内。 电解质中1,10-菲咯啉一水合物的浓度控制在0.05g / L-7.5g / L的范围内。
