Abstract: A method of producing a mercury-free corrosion resistant dendritic zinc alloy powder is provided. According to the method an electrolytic cell is prepared that contains an aqueous alkaline electrolyte with a preselected concentration of dissolved zinc cations and optionally the cations of one or more soluble inhibitor metals.

The second anode comprises an inhibitor metal, the salts of which are only sparingly soluble in the alkaline electrolyte. For example, the second anode may comprise a minor anode of indium or bismuth interposed between the first or major anode and the cathode. A first voltage between the first anode and cathode is then applied to establish a desired cathode current density and the deposition of dendritic zinc and optional soluble inhibitor metals on the cathode.
