ABSTRACT:
A sintering method for valve metal powders, such as tantalum, niobium, aluminum, titanium, and their alloys, is described. The valve metal powders are pressed into a pellet and sintered at a relatively high temperature, but for a relatively short time. The anodized valve metal structure is then useful as an anode in an electrolytic capacitor.
