Document Type and Number:
WIPO Patent Application WO/2018/066722
Kind Code:
A1
Abstract:
The present invention relates to a manufacturing method for a flake silver powder, the method comprising a flaking step (S2) of obtaining a flaked powder by milling through beads using an agglomerated silver powder as a raw material powder, wherein the agglomerated silver powder has an average diameter of 2.0 to 10.0 μm and a specific surface area of 1.0 to 2.5 m2/g by agglomerating primary silver particles having a diameter of 0.1 to 0.8 μm. Provided according to the present invention is a manufacturing method wherein, by using an agglomerated powder rather than a spherical powder as a raw material powder, a general-purpose milling device and beads are used to produce, at low cost, a uniform and fine flake silver powder which exhibits no agglomeration between powders and exhibits excellent electrical conductivity thanks to the wide contact area between the particles.
