SILVER POWDER

摘要

The present invention relates to a silver powder comprising silver nanoparticles each having a particle diameter of the nano-meter order (1 to 100 nm), and provides a novel silver powder having an excellent low-temperature sintering property. Proposed is a silver powder having a D50 value of 60 to 150 nm as determined by the image analysis of a scanning electron microscope (SEM) image, having a carbon (C) content of less than 0.40 wt% as determined in accordance with JIS Z 2615 (a method for quantitating carbon in a metallic material - general), and comprising truly-spherical or almost-spherical silver powder particles.
