Abstract
Provided are a silver powder having powder physical properties enabling reduction of volume resistivity after firing and a method of producing this silver powder. The silver powder has a tap density of 4.8 g/mL or more, a TAP/D50 value (value determined by dividing the tap density (g/mL) by the volume-based median diameter (μm)) of not less than 7 and not more than 15, and a specific surface area of not less than 0.75 m2/g and not more than 1.3 m2/g.
Claims6
A silver powder having:
- a tap density of 4.8 g/mL or more;

- and
- a specific surface area of not less than 0.75 m2/g and not more than 1.3 m2/g.
