<p><P>PROBLEM TO BE SOLVED: To provide silver-coated nickel powder having a low powder resistivity, and to provide the silver-coated nickel powder by a simple and low-cost method. <P>SOLUTION: The silver-coated nickel powder is characterized in that silver is comprised by 5 to 15 pts.mass based on 100 pts.mass of the total of the silver and nickel, and the resistance value of the powder under pressure of 5.6 MPa is 0.1 to 0.5Ω.mm. The silver-coated nickel powder can be produced by a process of reacting a solution (A) comprising nickel powder and a reducing agent with a solution (B) comprising a silver nitrate ammonia complex and a reaction inhibitor. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
