Title:
SILVER POWDER AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/191001
Kind Code:
A1
Abstract:
Provided are: a silver powder having powder physical properties capable of reducing volume resistivity after firing; and a production method therefor. This silver powder has: a tap density of at least 4.8 g/mL; a TAP/D50 value, obtained by dividing the tap density (g/mL) by a volume-based median diameter (μm), of 7-15; and a specific surface area of 0.75 m2/g to 1.3 m2/g.
