Optimization of the Process of Obtaining Electrocorundum Particles by Electrodispersing AD0Е Grade Aluminum Waste in Water

Purpose. Optimization of the process of obtaining electrocorundum particles by electroerosive dispersion of waste electrical aluminum grade AD0E in distilled water.

Methods. Electrodispersion of aluminum waste of the AD0E brand was carried out in distilled water on an original patented installation. As a result of exposure to short-term electrical discharges, droplet-like particles of electrocorundum of various sizes were formed. At the same time, the shape of the electrocorundum particles was examined on a scanning microscope, and the average particle size was examined on a laser analyzer. 

Optimization of the production process of droplet-like particles of electrocorundum by electroerosive dispersion of electrical aluminum waste of the AD0E brand was carried out according to the average particle size, since it is one of the main technological parameters of powder materials. To optimize the process of producing electrocorundum particles by electrodispersing aluminum waste of the AD0E brand, the method of steep ascent by Box and Wilson was used.

The adequacy of the equations was checked using the Fisher Criterion. 

Results.In accordance with the goal aimed at optimizing the production process of electrocorundum particles by electroerosive dispersion of electrical aluminum waste of the AD0E brand in distilled water, it was found that the optimal average size of electrocorundum particles is 74.2 microns with a discharge capacitance of 65.5 UF, a voltage at the electrodes of 200 V and a pulse repetition frequency of 200 Hz. 

Conclusion. The high efficiency of the use of electrodispersing technology is shown, which provides, at low energy costs, the production of commercially suitable new electrocorundum powder particles with spherical and elliptical shapes. Carrying out the planned measures will solve the problem of reducing the cost of production of electrocorundum.
