Document Type and Number:
WIPO Patent Application WO/2013/136615
Kind Code:
A1
Abstract:
Provided is a novel silver powder which can enhance the silver concentration of a silver paste and which can form a homogeneous sintered conductor having a lower electric resistance. Proposed is a silver powder characterized in that: the SEMD50 of the powder is 2.50 to 7.50μm; and the SEMD10, SEMD50 and SEMD90 of the powder satisfy the relationship (SEMD90- SEMD10)/SEMD50 ≤ 0.50. The term "SEMD10" "SEMD50" and "SEMD90" refer respectively to D10, D50 and D90 as determined by image analysis with a scanning electron microscope (SEM).
