Title:
METHOD FOR PRODUCING METAL PARTICLE COMPOSITION, AND METAL PARTICLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/071335
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for producing a metal particle composition, which makes it possible to produce metal material particles having a narrow particle size distribution in a metal material having lower hardness than silicon. The solution for the problem is a method for producing a metal particle composition comprising metal material particles, a component derived from a grinding container and a component derived from beads, the method comprising the step of stirring and grinding a metal material containing a metal having Mohs hardness of 2.5 to 6.3 in a grinding container in the presence of beads that serve as a grinding medium using a medium-agitation-type grinder equipped with a rotating body, the ratio of the mass of the metal material to the mass of the beads is 0.02 to 0.10 and the peripheral speed of the rotating body is 2.5 to 8.5 m/s.
