Velichenko, Доктор хімічних наук Registration Date 27-03-2017 Organization State higher educational entity "Ukrainian State University of Chemical Technology" popup.description2 Object of the investigation - regularities of phase regroupings in oxide-coated materials on the basis of PbO2. Aim - establishment of regularities of processes of recrystallization and phase regroupings in electrodes on the basis of PbO2 in processes of the long-lived electrolysis and cyclic polarization. Research methods - scanning submicroscopy, x-ray phase analysis, powder x-ray diffraction. It is established that the coverings received from the metansulfonathe electrolytes are polycrystalline and are characterized by the smaller sizes of crystals. In the conditions of the long-lived electrolysis the materials on the basis of PbO2 besieged from the metansulfonathe electrolytes remain stable and practically do not change the phase structure and morphology of a surface. Depending on concentration of lead methansulfonathe in electrolyte and hydrodynamic conditions of carrying out process it is possible to besiege qualitative not intense settlings with a good adhesion to a substrate to 2 mm in the range of current densities of 2 - 180 mA/cm2. Change of composition of metansulfonathe electrolyte and conditions of an deposition influences phase composition of lead dioxide. The main difference from the oxides received from nitrate solutions is the considerable maintenance of a alfe-phase which can will change ranging from 17 to 90%. Area of application: C 20.13 - production of other main inorganic chemicals; М 72.19 – research and experimental development in the field of humanitarian and technical sciences.
