METHOD FOR MANUFACTURING SILVER NANOPARTICLES AND ELECTRICAL CONTACT MATERIAL COMPRISING SILVER NANOPARTICLES MANUFACTURED THEREBY

Document Type and Number:

WIPO Patent Application WO/2020/111340

Kind Code:

A1

Abstract:

The present invention relates to a method for manufacturing silver (Ag) nanoparticles by using a plasma method and to an electrical contact material comprising the silver nanoparticles. Silver nanoparticles are formed by feeding a silver raw material to a silver-based plasma mold in a reaction chamber and controlling a degree of vacuum and plasma power, whereby the silver nanoparticles can be rapidly manufactured and can be easily controlled in terms of the size and composition thereof.
