In this work, the technological aspects of great importance YBa_2Cu_3O_{7-x} superconducting materials were produced in the form of nanotube by electrochemical method. The electrochemical deposition conditions for the Y-Ba-Cu deposition in nanoporous Al_2O_3 were investigated. The heat treatment was applied to Y-Ba-Cu/Al_2O_3 nanopatterns, to form superconductive phase. The resulting nanostructures were found to be in length 4-5 μm, 177-210 nm in diameter. The produced nanostructures at - 4 V and more positive potentials were Y-Ba-Cu nanowires, while the nanostructures deposited at the more negative potentials were of nanotube form.
