Abstract

A non-amalgamated zinc alloy powder for use in an alkaline cell which consists essentially of an elemental component selected from among the following compositions (1) to (4);
(1) 0.001 to 0.5 % by weight of aluminum and 0.01 to 0.5 % by weight of bismuth, (2) 0.001 to 0.5 % by weight of aluminum, 0.01 to 0.5 % by weight of bismuth and not more than 1.0 % by weight of indium, (3) 0.001 to 0.5% by weight of aluminum, 0.01 to 0.5 % by weight of bismuth and not more than 0.5 % by weight of lithium, and (4) 0.001 to 0.5 % by weight of aluminum, 0.01 to 0.5 % by weight of bismuth, not more than 1.0 % by weight of indium, and not more than 0.5 % by weight of calcium or not more than 0.5 % by weight of lithium;
and the balance being zinc and containing iron as an inevitably accidental impurity in an amount of not more than 1 ppm; and which can greatly suppress the evolution of hydrogen gas and maintain the discharge performance on a practical level:
and a method to produce the same.
