For the preparation of copper nanoparticles several methods, i.e., thermal reduction, mechanical attrition,
chemical reduction metal vapour synthesis, radiation methods, laser ablation
and micro emulsion techniques were developed
in the past. Electrolytic deposition is one of the most suitable,
simplest and low cost methods which are used for wide range of materials. In
the present investigations, efforts were put
to produce copper nano powder using electrolytic technique. It could be
possible to obtain near nano copper powder of 258 nm size using high cathode
current density of 1100 A/m2 in sulphate bath. The specific surface
area and shape of the particles were found to be 23.2 m2/g and irregular,
