|Title:||Electrowinning of copper powder from copper sulphate solution in presence of glycerol and sulphuric acid|
|Authors:||Viswanath, S G|
|Abstract:||Copper powder was obtained by electrowinning copper from glycerol and sulphric acid medium. The morphology and particle size of these powders were studied. Dendrites were observed in the powder obtained from solutions containing only glycerol. Powder obtained from the sulphuric acid glycerol medium the particles were spherical or round in shape and more than 90% of particles were below 100 µm. The nano-particles were also observed that were in the range of 200-700 nm. The apparent density of copper powder decreased with increasing concentration of sulphuric acid and glycerol that might be helpful in assessing the nature and particle size. The stability of the powder and current efficiency were also studied.|
