ABSTRACT:
Corrosion is reduced in aqueous electrochemical cells having zinc anodes by utilizing mercury amalgamated discrete single crystal zinc particles to which small amounts of one or more of indium, thallium, gallium, bismuth, cadmium, tin and lead have been added or prealloyed with the zinc, prior to formation of the single crystal particles. A synergistically lowered rate of corrosion and cell gassing is obtained even with reduction of mercury content.
