NICKEL ALLOY POWDER, AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide nickel-silver alloy powder having excellent properties as nickel alloy powder for electroconductive paste having excellent oxidation resistance. SOLUTION: In the nickel alloy powder consisting essentially of nickel, comprising 0.1 to 30 atomic% silver and having a mean particle diameter of 0.1 to 2μm, silver is segregated in the vicinities of the surfaces of the particles, and it is used as the one for electroconductive paste having excellent oxidation resistance. The powder can be produced by charging the chloride 21 of nickel and the chloride 22 of silver into a reaction vessel 11, feeding a carrier gas 13 and a reducing gas 12 therein while being held in a high temperature atmosphere and causing chemical vapor phase reaction in an alloy powder production region 15.
