Abstract
The present invention relates to the field of solid state capacitors, and in particular to capacitors that have an anode body formed of porous valve action material, such as tantalum, niobium or niobium monoxide. According to one aspect of the present invention, there is provided a method of forming capacitor anode bodies from valve action material comprising the steps of: providing a capacitor grade powder of the valve action material, charging the powder into a press mold, compacting the powder in the mold so as to shape the powder into an anode body shape, stabilizing the body shape, for example by sintering of the material to form an inter-connected porous body, characterized in that the molding process involves the use of a lubricant applied locally to lubricate the interface between an outside surface of the anode body and a molding surface of the mold.
