Abstract

전해에 의한 금속박 제조 방법이 발표되어 있는데, 박막 형성 금속 기판상에 형성된 산소 불침투성 코팅으로 이리듐과 탄탈의 혼합 산화물로 구성된 전극 활성 코팅을 가지는 불용해성 전극을 양극으로 사용하는 것과, 상기전해 용액속의 불순물이 상기 양극상에 불용해성 산화물을 형성하는 전위보다 높은 양극 전위에서 상기 전해 용액속의 불순물을 양극상에 침착시키는 것을 포함한다.A method for producing a metal foil by electrolysis has been disclosed, which uses an insoluble electrode having an electrode active coating composed of a mixed oxide of iridium and tantalum as an anode, and an oxygen impermeable coating formed on a thin film-forming metal substrate. Depositing impurities in the electrolytic solution on the anode at an anode potential higher than that at which the impurities form insoluble oxides on the anode.
