An improved process for forming powder, an anode of the powder and a capacitor comprising the powder is provided. The process comprises forming a dense aggregate comprising a powder and solvent in a pendular, funicular or capillary state and freeze drying the powder comprising high surface area.

Method of producing a tantalum capacitor anode

An improved capacitor, and method of manufacturing the improved capacitor, is provided. The method includes deoxygenating and leaching the anode wire to produce a capacitor comprising an anode having a surface area of at least 4.0 m/g or a charge density of at least 200,000 CV/g with the anode wire having an equivalent diameter of less than 0.30 mm extending from said anode. A dielectric is on the anode and a cathode is on the dielectric.

Method to reduce anode lead wire embrittlement in capacitors

A process for providing an improved hermetically sealed capacitor which includes the steps of applying a solder and a flux to an interior surface of a case; flowing the solder onto the interior surface; remove flux thereby forming a flux depleted solder; inserting the capacitive element into the casing; reflowing the flux depleted solder thereby forming a solder joint between the case and the solderable layer; and sealing the case.
