Nickel powders were prepared from nickel chloride solution by wet reduction process, and the size control of the particles was investigated with reactant concentration, dispersant agent, and the addition of ethanol as an organic solvent in NiCl 2 aqueous solution. The size of the particle decreased with the increase of nickel chloride concentration. Their average particle size were 1.9 μm , 1.6 μm and 1.5μm with 0.5M, 0.8M and 1.0M of nickel chloride concentration respectively. The spherical particle was easily controlled by the addition of ethanol as an organic solvent. Especially, in 30 vol% of ethanol, the average particle size and specific surface area were about 0.2 μm and 8.98m 2 /g, respectively.

Keywords:Nickel powder;Size control of the particles;Wet reduction process
