Abstract

The paper presents the results of a study of the particles obtained from the synthesized cathode dry deposits. It is noted that the amount of the obtained residual particles can vary within wide limits. At the same time there is the predominance of octahedral and cuboktahedral forms of the particles in the dimension characteristic for fine and ultrafine powders. X-ray diffraction analysis showed the prevalence of oxide copper (I) in these forms. The variation of process parameters, especially the reduction of the current density of the process and therefore reduction of the current density at the cathode lead to reducing the size of the resulting particles and improving uniformity of deposits, as evidenced by the results of electron microscopic studies of the synthesized cathode deposits. This allows controlling the process of synthesis of particles by adjusting the process parameters of plasma chemical treatment, which due to its constructive design isn’t cause difficulties and, along with the possibility of using very dilute solutions, is the advantage of this method.
