Paper Title:
The Experiment Study on Making Ultrafine Superfine Nickel Powder by N2H4–KHB Reduction and H2 Reduction
  Abstract

The N2H4–KHB reduction then CH3OH watering and H2 reduction system was used to make superfine nickel powder by using nickel sulfate as material.The superfine nickel powder of the specific surface area of the nickel powde being 4.24m2/g, spheric shape with grain size 0.5-0.9μm,nickel content being over 99.5%,The toll nichel recovery being over 99.5% was made on the condition of reaction temperature 60°C, reaction time 150-180min,pH 8.0-8.5,[Ni]=1.25M,N2H4/Ni=1.35(mol ratio),sodium hexametaphosphate of 1.5‰ as additive,the dosage of KHB of 8.37×10-3g/g Ni and washing by carbinol,reducing by H2.
