Abstract
1307149 Electrolytic capacitors V V VAVILOV V G GERLIVANOV A A PANOV P A PRUDNIKOV A S SAKHIEV and M I KHLOPIN 23 June 1971 [23 July 1970(2)] 29477/71 Heading H1M In the manufacture of an electrolytic capacitor, aluminium particles having an oxide coating les than 100Š thick are prepared by atomizing molten aluminium in an oxidizing atomsphere, removing the particles from the oxidizing atmosphere by directing them into liquid hydrocarbon, sintering the coated particles to form anode 1, and electrolytically forming dielectric layer 3. The aluminium may be commercial grade, or alloyed with up to 3% of tantalum, titanium, zirconium, or niobium. Layer 2, comprising e.g. pyrolytic manganese dioxide, and contact layers 5 and 6 are applied in standard fashion.
