摘要:
The present invention provides a method for producing a silver powder, the method being capable of producing a silver powder with high productivity and at low cost, the silver powder having an average particle diameter of 0.3 to 2.0 μm and a narrow particle size distribution, and provides a silver powder produced by the production method. According to the present invention, the method for producing a silver powder includes: quantitatively and continuously supplying each of a silver solution containing a silver complex and a reductant solution to a flow path; and quantitatively and continuously reducing a silver complex in a reaction solution obtained by mixing the silver solution with the reductant solution in the flow path, wherein the reaction solution is made to contain a dispersant, and also a silver concentration in the reaction solution is adjusted to be in a range of 5 to 75 g/L.
