Title:
CONDUCTIVE POWDERY MATERIAL, CONDUCTIVE MATERIAL CONTAINING SAME, AND METHOD FOR MANUFACTURING CONDUCTIVE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2010/044388
Kind Code:
A1
Abstract:
Provided is a conductive powdery material having excellent dispersibility and conductivity, even though the particle diameter of the conductive powdery material is smaller than the particle diameters of conventional conductive powdery materials.
The conductive powdery material is composed of conductive particles each of which has a nickel film or a nickel alloy film formed on the surface of a core particle. The conductive particle has many protruding sections, each of which protrudes from the surface of the film, is formed continuous to the film, and has an aspect ratio of 1 or more. The ratio of the protruding sections having an aspect ratio of 1 or more is 40% or higher with respect to the total number of protruding sections. As for the conductive powdery material, the weight of the primary particles among the conductive particles is 85 wt% or more with respect to the weight of the conductive powdery material.
