Abstract
1507667 Electrolytic capacitors STANDARD TELEPHONES & CABLES Ltd 10 June 1975 [20 June 1974] 27378/74 Heading HIM An electrolytic capacitor anode comprises a compacted porous body of valve metal coated particles, the particles being non- conducting non-combustible, irregularly shaped, and the valve metal coating being such that after anodizing the average thickness of the part of the coating remaining unanodized is not more than 0À5Á. Particles of ceramic, e.g. alumina, of average diameter 2À5 to 30Á may be coated with tantalum to a thickness of, e.g. 0À5Á by vapour phase reduction of tantalum pentachloride in a fluidized bed, the coated particles pressed and sintered and the body so formed anodized at a voltage determined by the required working voltage of the capacitor.
