Title:
METHOD FOR PRODUCING LOW-MELTING-POINT METAL NANOPARTICLES
Document Type and Number:
WIPO Patent Application WO/2011/114579
Kind Code:
A1
Abstract:
Provided is a method for producing low-melting-point metal nanoparticles, which can produce low-melting-point metal nanoparticles without using a high-vacuum container and which can produce alloy nanoparticles having a stable metal composition ratio. Specifically, provided is a method for producing low-melting-point metal nanoparticles, which involves: a step for obtaining a mixture by placing a solid or liquid low-melting-point metal, a non-water-based solvent, and pulverization balls having a diameter of 0.015mm to 5mm in a container; a step for stirring and heating the aforementioned mixture between the temperatures of -5°C to +20°C of the melting point of the aforementioned low-melting-point metal; a step for separating the aforementioned pulverization balls from the stirred mixture, and for obtaining a mixture of low-melting-point metal nanoparticles and the non-water-based solvent; and a step for performing solid-liquid separation on the mixture of the low-melting-point nanoparticles and the non-water-based solvent, and for obtaining low-melting-point nanoparticles.
