MANUFACTURING METHOD OF METAL PARTICLE AND METAL PARTICLE USING THEREOF, AND CONDUCTIVE PASTE AND SHIELDING ELECTROMAGNETIC WAVE CONTAINING THE SAME

摘要

The present invention relates to a method for manufacturing a metal particle and a metal particle manufactured thereby. According to the present invention, the method for manufacturing a metal particle is capable of coating the surface of the metal particle with a silver nanoparticle by adding a metal particle and a reducing agent to a first reaction solution including a silver precursor and an organic stabilizer; and manufacturing conductive paste and a high conductivity material for electromagnetic wave shielding using the method. Furthermore, a silver coated metal particle doped with silver can be manufactured by doping a silver nanoparticle inside a metal particle from a second reaction solution including a silver precursor, a copper precursor, and an alcohol solvent; and conductive paste with improved conductivity and a high conductivity material for electromagnetic wave shielding can be manufactured by containing the silver coated metal particle on which silver is doped.
