Method of manufacturing an anode zinc can for a manganese dry battery |
摘要 |
The present invention provides a method of manufacturing a zinc-titanium mother alloy and a manganese dry battery having an anode zinc can prepared from the zinc-titanium alloy. The method comprises: adding spongy titanium to molten zinc; and melting the spongy titanium to alloy with the zinc at 500 to 750 DEG C for 0.5 to 6 hours, thereby to obtain a zinc-titanium alloy which contains 0.001 to 5% by weight of titanium. The anode zinc can prepared from the zinc-titanium mother alloy is substantially free from metallic titanium and intermetallic compounds having the Zn-Ti atomic ratio of not less than 1/2. <IMAGE> |
