Title:
METAL NANOPOWDER COMPRISING SOLID SOLUTION OF SILVER AND COPPER
Document Type and Number:
WIPO Patent Application WO/2020/045728
Kind Code:
A1
Abstract:
The present invention relates to a metal nanopowder comprising a solid solution of silver and copper and, more specifically, to a metal nanopowder, which: can have a remarkably reduced oxidation rate compared with that of a single metal even if exposed to air since the metal nanopowder is present in a metal nanopowder form formed from a solid solution of silver, which is crystalline and has a multiphase and uniform porosity, and copper, which is amorphous, thereby exhibiting excellent corrosion resistance; and exhibits excellent conductivity even in a powder form, thereby having a remarkably lower electric resistance compared with that of silver, which exhibits the lowest electric resistance from among metals.
