Filed: 2001-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a production method for aluminum foil for an electrolytic capacitor electrode in order for obtaining an electrode foil for an electrolytic capacitor with a high electrostatic capacity. SOLUTION: Aluminum foil (coil) is put in an annealing oven. Before the step of raising the inside temperature of the annealing oven to a specified value, air is exhausted from the annealing oven to reduce the inside pressure to 50 Pa or lower and an inert gas such as a nitrogen gas, an argon gas, or a helium gas is introduced into the oven. The amount of the inert gas introduced is set so that the inside pressure reaches the atmospheric pressure or higher. Then, the temperature-raising step is started. After starting the temperature-raising step and before ending the step, the inert gas in the oven is replaced with a reducing gas containing at least 10 vol.% hydrogen gas. The amount of the reducing gas is also set so that the inside pressure reaches the atmospheric pressure or higher.  After the completion of the temperature-raising step, the aluminum foil is subjected to a holding step, a cooling step, and the final annealing step, thus giving the aluminum foil for an electrolytic capacitor electrode.
