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 burning time was determined as a function of particle diameter by processing video recordings of the combustion process. The morphological and granulometric characteristics of condensed products (large residues of agglomerate combustion) — the final oxide particles—were analyzed. The relations between the diameters and masses of the oxide residue and the initial agglomerate particle were determined. An empirical formula for estimating the density of the final oxide particles is proposed.
