| Description |
The present invention relates to a process for the manufacture of a novel cermet anode useful for eco-friendly electrolytic extraction of metals, such as aluminum, from fused salts. The process provides a novel cermet anode which consists of compositions of mixed oxides of transition and rare earth metals in combination with metal powders, without any binders, and is amenable to high-pressure compacting and high temperature sintering methods. The novel cermet anode manufactured by the process of the present invention is thermally stable at 1000° C, is chemically inert and non-consumable in a cryolite melt and does not contaminate the cathode product, has low and high anodic over voltages for oxygen and fluorine evolution, respectively, and is dense and resistant to oxidation.
