Abstract:
1. A producing method for an Ag or Ni conductive powder having a convex radially extended and a concave among the convex, wherein a core material to strengthen the crystal reaction such as Ag or Ni, which is at least one particle selected from the group consisting of an organic particle, a metal particle and a ceramic particle and which concentration is within a range of 0.01 to 30 wt. % based on the total weight of the conductive powder is included into the conductive powder by using the solution reduction method, wherein the following steps (a) to (b) are included: (a) preparing a core material to strengthen the crystal reaction such as Ag or Ni, (b) forming an Ag or Ni conductive powder by reacting Ag nitrate or Ni nitrate with a reduction agent in the presence of the core material.
