Heterogeneous copper - method of synthesizing nickel complexes

摘要

A non-homogeneous copper-nickel composite and a method for synthesizing the same are disclosed. The non-homogeneous copper-nickel composite includes a higher amount of nickel in a surface portion of the composite than in a center portion thereof. The non-homogeneous copper-nickel composite exhibits sufficient oxidation resistance to prevent deterioration in electrical conductivity thereof due to an oxide layer formed on surfaces of particles during sintering while exhibiting a similar level of electrical conductivity to silver particles. In addition, the non-homogeneous copper-nickel composite can exhibit high adhesion to a coating metal layer.
