摘要：

The paper solves the problem of alumina bubble production. This problem is proposed to be solved by electrodispersion of AD0E grade electrical aluminum waste in distilled water. To develop technologies for reuse of the obtained alumina bubble and to assess the efficiency of its utilization requires complex theoretical and experimental studies. The purpose of the work was to study the structure and properties of alumina bubble obtained by electrodispersion of AD0E grade electrical aluminum waste in distilled water. The tasks set in this work, aimed at studying the structure and properties of alumina bubble obtained by electrodispersing AD0E grade electrical aluminum waste in distilled water, were solved using modern equipment and complementary methods of physical materials science: the shape and surface morphology of fused alumina particles were investigated on an "QUANTA 600 FEG" electron-ion scanning microscope with field emission of electrons (Netherlands); the elongation coefficient and particle size distribution of powder particles were investigated on a "Analysette 22 NanoTec" laser particle size analyzer (Germany); X-ray spectral microanalysis of powder particles was performed on the "EDAX" energy dispersive X-ray analyzer (Netherlands), integrated into the "QUANTA 200 3D" scanning electron microscope (Netherlands); phase analysis of powder particles was performed on the "Rigaku Ultima IV" X-ray diffractometer (Japan). It was found experimentally that spherocorundum has the following characteristics: shape - spherical, elliptical and agglomerates; volume-average particle diameter is 42.6 mu m; particle surface is oxygen clad; phase composition consists of Al2O3 and Al(OH)3.
