Abstract
Dcke-karbon metallbasert anode i en celle for elektrolytisk utvinning av aluminium, omfattende et elektrisk ledende metallsubstrat bestandig mot høy temperatur, hvor overflaten blir passiv og i hovedsak inert mot elektrolytten, og et belegg vedheftet på metallsubstratet og som gjør overflaten på anoden elektrokjemisk aktiv for oksidasjon av oksygenioner til stede ved elektrolyttgrenseflaten. Metallsubstratet kan velges blant nikkel, kobolt, krom, molybden, tantal og lantanrekken. De aktive bestanddeler i belegget er for eksempel oksider slik som spineller eller perovskitter, oksyfluorider, fosfider eller karbider, især ferritter. De aktive bestanddeler kan belegges på substratet fra en slurry eller suspensjon inneholdende kolloidalt materiale og det elektrokjemisk aktive materiale.Dcke-carbon metal-based anode in a cell for electrolytic recovery of aluminum, comprising an electrically conductive metal substrate resistant to high temperature, where the surface becomes passive and mainly inert to the electrolyte, and a coating adhered to the metal substrate and which makes the surface of the anode electrochemically active for oxidation of oxygen ions present at the electrolyte interface. The metal substrate can be selected from nickel, cobalt, chromium, molybdenum, tantalum and the lanthanum row. The active ingredients in the coating are, for example, oxides such as spinels or perovskites, oxyfluorides, phosphides or carbides, in particular ferrites. The active ingredients may be coated on the substrate from a slurry or suspension containing colloidal material and the electrochemically active material.
