Abstract
PURPOSE:To produce mercurated zinc alloy powder for alkali dry cell without any contamination in working environment by mixing Al, Ni, alkali metal, In, etc., with molten Zn, making zinc alloy powder and executing dry type mercuration to this with mercury. CONSTITUTION:To the molten Zn, about 0. 001-0.2wt.% Al, about 0. 001-0. 5wt.% Ni and/or Co, about 0.0005-0.5wt.% alkali metal and/or alkali earth metal and if necessary, one or more kinds selected among In, Pb, Cd, Tl and Ga are mixed to make the Zn alloy powder by atomization. Then, the alkali metal and the alkali earth metal use >=7 kinds selected among Li,Na, K, Rb, Be, Mg, Ca, etc. The dry type mercuration is executed to this Zn alloy powder with Hg or Hg compound (Hg and Pb, etc.) and the mercurated Zn alloy powder having <=about 3.0wt.% Hg content is produced. By this method, at the time of using to cathode active material for the alkali dry cell, the mercurated Zn alloy powder, which gas generation is restrained by low mercuration, is obtd.
