The production mannered null silver nitrate solution and the reducing agent solution

摘要

PROBLEM TO BE SOLVED: To provide a producing method in which high crystalline flaky silver powder which is extremely fine, and uniform in the shape and the size can easily be obtained by a wet type reducing method without using a pulverizing process.;SOLUTION: In the method for producing the high crystalline flaky silver powder, silver nitrate solution is allowed to react with a reducing agent solution in the presence of (A) ethylenediaminetetraacetic acid and/or its salt, (B) at least one kind of compound selected from a group consisting of a carboxylic acid, a carboxylic acid metal salt, a carboxylic acid anhydride and a carboxylic amide, and (C) a copper compound.;COPYRIGHT: (C)2006,JPO&NCIPI
