Title: METHOD FOR PREPARING NICKEL NANOPOWDERS AND METHOD FOR MAKING NICKEL NANOPOWDERS INTO PASTE
Abstract:
A method of making nickel nanopowders into paste is introduced. To this end, the present invention relates to a method for making nickel nanopowders into paste comprising: (a) a step of preparing a nickel oxide in the form of an oxide; (b) a nickel oxide nanopowder preparing step of 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 pure metal nickel nanopowders by preparing the nickel oxide nanopowders as the pure 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 pulverizing the pure metal nickel nanopowders produced by the heat treatment and a nanopowder anti-oxidation coating step of forming an anti-oxidation film on the pure metal nickel nanopowders with an additive; and (f) a step of making the pure metal nickel nanopowders, which have been simultaneously subjected to the pulverizing and coating steps, into paste.
