Regularities of copper's Nano powders receiving by an electrolysis method in ammine electrolyte, with the soluble copper anode and the corrugated titanic cathode are investigated. With additional use of polyacrylamide as the stabilizer of particles' growth of Nano powder of polyacrylamide. It is shown that in the polyacrylamide's presence the share of Nano dimensional fraction of copper's powder raises and the contents in the final product of copper`s oxides decreases. To what Nano powders' roentgenograms testify.
