Beschreibung
Zusammenfassung:	Improved anodes for solid electrolytic capacitors are produced by introducing in the anode body made of a film forming sintered metal powder one of the following additives : tungsten, molybdenum, vanadium and hafnium, at the most suitable step of the manufacturing process previous to sintering under one of the following forms : pure metal, oxide, sulphide. In a preferred embodiment the additive is introduced in the binder used for pelletizing. In another embodiment the additive is introduced by dipping the presintered anodes in a solution containing said additive.
