Abstract
A method of making a porous metallic electrode element for an electrolytic capacitor comprises mixing powdered carbon, e.g. graphite, and a powdered oxide of an anodizable metal, e.g. tantalum, columbium, tungsten, titanium, zirconium and hafnium, which is reducible by reaction with carbon, comminuting the mixture, e.g. by ball milling, to an average particle size in the range 0.5-2 microns, confining the mixture in a mould, exerting pressure, e.g. 2000 lb./inch2, on the confined mixture to produce a shaped compact, and heating the compact under sub-atmospheric pressure, e.g. 1 micron Hg, to a temperature, e.g. 1800-2000 DEG C, exceeding that necessary to induce incipient reaction between the oxide and the carbon and produce an element having a density in the range of 4-7 grams/cm.3. An electrical conductor made of metal similar to that of the electrode may be attached thereto by inserting the conductor in the mould before the mixture of powder is introduced. The electrode is anodized, in a known manner, after its heat treatment. Specification 857,752 is referred to.
