Abstract

A process for producing a copper powder which has a particle size distribution with an extremely narrow width and is reduced in impurity content; and a copper powder which is obtained by the process, has heightened conductivity, is homogeneous, and has high quality. The process for copper powder production comprises: adding a hydrazine-based reducing agent to a copper salt compound slurry obtained by adding an alkali solution to an aqueous copper salt solution to obtain a slurry of cuprous oxide; washing the cuprous-oxide slurry with water and slurrying the oxide again; and adding a hydrazine-based reducing agent again to the resultant slurry of the washed cuprous oxide. In this process, a phosphorus compound is added to the reaction slurry before completion of the final reduction reaction so as to result in a phosphorus/copper molar ratio, P/Cu, in the range of 0.0001-0.003.
