PURPOSE:To provide zinc alloy powder for an alkaline battery and its manufacture, capable of sharply restraining hydrogen gas generation and also of retaining discharge performance in a practical level in a non-mercuriged condition. CONSTITUTION:Zinc alloy powder for an alkaline battery and its manufacture have a feature of containing a iron of 5ppm and less and components selected from the following (1) or (2); (1): bismuth of 0.01-0.5wt.%, indium of 0.01-0.5wt.%, and at least one kind of total 0.05-0.1wt.% selected from magnesium, zirconium, lithium, lanthanum, barium, silicon, boron, and tantalum; (2): aluminum of 0.01-0.5wt.%, indium of 0.01-0.5wt.%, and at least one kind of total 0.005-0.1wt.% selected from magnesium, zirconium, lithium, lanthanum, barium, silicon, boron, and tantalum. |
