Claims14
An electrode for an electrowinning cell for electrolysis of an acid medium in which the anodically active material is formed of an alloy of titanium and nickel, the nickel content being in the region of 51 to 55 wt% of the sum of the titanium and nickel contents.
A method of electrowinning a metal from an electrowinning cell containing an aqueous solution of ions of that metal which comprises inserting an anode and a cathode into the solution the anode being formed of an alloy of titanium and nickel, the nickel content being in the region of 51 to 55 wt% of the sum of the titanium and nickel contents, and passing an electrical current between the anode and the cathode.
An electrode for an electrowinning cell for electrolysis of an acid medium in which the anodically active material is formed of an alloy of titanium and nickel, the nickel content being in the region of 51 to 55 wt% of the sum of the titanium and nickel contents, and tantalum or niobium in an amount between 0.1 and 5 atomic percent.
An electrode for an electrowinning cell for electrolysis of an acid medium in which the anodically active material is formed of an alloy of titanium and nickel, the nickel content being in the region of 51 to 55 wt% of the sum of the titanium and nickel contents, and 0.01 to 0.25 wt% of a metal chosen from the group consisting of platinum, iridium, ruthenium, rhodium and palladium.
