SYNTHETIC METHOD OF NANO-SIZED NI POWDER

摘要

The present invention relates to a method for preparing nickel nanopowder, and more particularly to preparing an aqueous nickel solution in which a water-soluble nickel salt, a nucleating agent and a dispersant are dissolved together, and adding a mixed solution of a surfactant and a cyclohexane to the microemulsion. It is composed of the step of warming and reducing the reaction with ammonia water and a reducing agent, quenching it and then adding a stabilizer and ethanol to separate the layers and centrifugation to recover the nickel nanoparticles and to dry.;The present invention has the effect that by applying the microemulsion method to the production of nickel nanopowder by the liquid phase method, the surface of the prepared nickel nanoparticles are surrounded by crystalline hydrazine salt to produce a more stable nickel nanopowder.
