Title:
TANTALUM FILAMENT USED FOR ANODE OF TANTALUM CAPACITOR AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/083632
Kind Code:
A1
Abstract:
A tantalum filament used for an anode of a tantalum capacitor, the cross section of the tantalum filament is approximate rectangular or regular rectangular. A manufacturing method of the tantalum filament, comprises the steps: performing heat treatment to the raw tantalum filament; performing surface treatment to the tantalum filament after being treated so that an oxide film is formed on the surface of tantalum filament; lubricating by means of lubricative oil and rolling the tantalum filament after being pretreated so that the cross section of the tantalum filament is approximate rectangular or regular rectangular; annealing the tantalum filament finally.
