COMPOSITION OF CHARGE FOR MANUFACTURE OF OXIDE-METAL INERT ANODE Russian patent published in 2015 - IPC C25C3/12 B22F5/00 

FIELD: metallurgy.

SUBSTANCE: invention can be used at manufacture of a composite oxide-metal inert oxygen-releasing anode for electrolytic obtainment of metals, and namely aluminium. Composition of a charge for manufacture of the above anode contains a mixture of oxide and metal components taken in the following ratio, wt %: metal component - 10-30, and oxide component is the rest. The oxide component includes a mixture of two or more microdimensional oxide powders taken from following row: nickel oxide, iron oxide, copper oxide and chrome oxide. The metal component includes microdimensional powders of copper or a copper-based alloy, as well as it contains 2-10 wt % of nanodimensional copper powder or the copper-based alloy with particle size of up to 100 nm.

EFFECT: invention allows increasing specific electric conductivity of an anode at the temperature of 750-850 °C and reducing its corrosion speed at low-temperature electrolytic production of aluminium from an oxide-fluoride melt.
