Abstract: A method for obtaining burning aluminum agglomerate particles with a diameter of 215–840 $\mu$m is described, and their combustion in free fall in air at atmospheric pressure has been studied. The combustion time as a function of particle diameter was determined by processing video recordings of the combustion process. The morphological and granulometric characteristics of condensed products (large residues of combustion of agglomerates) – final oxide particles were investigated. The ratios of the diameters and masses of the oxide residue and initial agglomerate particles were determined. An empirical formula for estimating the density of the final oxide particles is proposed.

Keywords: aluminum agglomerate, diameter, combustion in air, combustion time, oxide combustion residue of parent agglomerate particle, diameter and mass of oxide residue.
