Title:
METHOD FOR PRODUCING LOW-OXYGEN VALVE-METAL SINTERED BODIES HAVING A LARGE SURFACE AREA
Document Type and Number:
WIPO Patent Application WO/2014/167045
Kind Code:
A3
Abstract:
The invention relates to a method for producing sintered bodies from valve metals, in particular tantalum, which sintered bodies have a low oxygen content and good tear-off resistance of the wire embedded in the anode body despite the large surface area of the sintered bodies.
