Patent ID: 11090722

Abstract:
Provided is a method for making nickel nanopowders into paste including: (a) preparing a nickel oxide configured in the form of an oxide; (b) preparing nano-sized nickel oxide nanopowders by pulverizing the nickel oxide; (c) a step of drying the nickel oxide nanopowders; (d) a step of preparing natural metal nickel nanopowders by preparing the nickel oxide nanopowders as the natural metal nickel nanopowders through a reduction process in a hydrogen atmosphere and heat-treating the same at the same time; (e) a step of simultaneously performing a step of crushing the natural metal nickel nanopowders prepared by the heat treatment and a nanopowder oxidation preventing coating step of forming an oxidation preventing film on the natural metal nickel nanopowders with an additive; and (f) a step of making the natural metal nickel nanopowders, which have been simultaneously subjected to the crushing and coating steps, into paste.
