Abstract
Mono-disperse and spherical Ni powders were prepared using a N2H4-based solution reduction route. The main focus was on manipulating the particle size by varying the source materials (Ni-chloride, Ni-sulfate and Ni-acetate) and impurity concentrations. The morphology and size of the Ni particle closely depended on the source materials. In addition, the particle size became significantly smaller with increasing Co concentration ranging from 0 to 350 ppm. The decrease in the Ni particle size was attributed to the promotion of nucleation by the rapid decomposition of the CoCl2–N2H4 complex when adding a NaOH solution and the more active reduction of Co than that of Ni in the initial stages of the reaction.
