“…Высокоперспективным экологичным методом переработки отходов никеля в порошки является метод электродиспергирования. Суть метода заключается в том, что токопроводящие металлические отходы измельчаются в дисперсный порошковый материал электрическими разрядами, возникающими между электродами [7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

The purpose of this study was to obtain electroerosive dispersed nickel by processing nickel waste by electrodispersing in isopropyl alcohol, as well as to study the performance of this process and the particle size of the obtained dispersed nickel.Methods. Nickel waste in the form of plates was processed into powder by electrodispersion at an experimental electroerosive dispersion plant (RF Patent No. 2449859) in an isopropyl alcohol medium. The study of the average particle size of the obtained electroerosive dispersed nickel was carried out using a laser particle size analyzer "Analysette 22 NanoTec".Results. For the first time, spherical nickel powders in the medium of isopropyl alcohol were obtained from industrial waste by the method of electroerosive dispersion. The parameters of the electroerosive dispersion unit necessary for the dispersion of nickel waste have been determined. A directly proportional dependence of the mass productivity of the process of electroerosion research of nickel waste dispersion on the voltage at the electrodes in isopropyl alcohol in the range of 120-220 V. has been experimentally established. The optimum for dispersing nickel waste in isopropyl alcohol is the voltage at the electrodes in the range of 200-220 V. It is established that the smallest particle size is nickel powder obtained at a voltage of 220 V at the electrodes, while the mass productivity at this value of the voltage at the electrodes is the maximum.Conclusion. Based on the presented experimental studies of the mass and quantitative productivity of the process of electroerosive dispersion of nickel waste in isopropyl alcohol, a high efficiency of the use of electrodispersion technology for obtaining dispersed nickel powder, which is not inferior to industrially used powders in terms of average particle size, has been established. It has been experimentally established that the smallest particle size has a nickel powder obtained at a voltage of 220 V on the electrodes, while the mass productivity at this value of the voltage on the electrodes is maximum.
