“…The complex mechanisms of aerosol droplet formation, drying, and thermolysis in a dynamic mode were studied in detail in [26]. It was shown that the morphology of particles when using the USP process is formed during drying and is retained during the subsequent calcination.…”

“…This work describes the most promising method of ultrasonic spray pyrolysis (USP). Previously, using the USP method, hollow microspheres of multiferroics BiFe 1−x Mn x O 3 were obtained and studied [26,27]. The USP method makes it possible to control the conditions for the formation of a single-phase oxide from an aqueous aerosol with a radial distribution of dissolved components in the droplet volume, which subsequently determines the formation of spherical agglomerates of a given diameter [26].…”

By varying the intensity of ultrasonic exposure, the temperature and atmosphere of aerosol thermolysis, it seems possible to obtain vanadium oxide in the expected valence and morphological state.…”

Vanadium oxides V 2 O 5 and V 2 O 3 have been synthesized by ultrasonic spray pyrolysis in the form of nanostructured spherical agglomerates with an average diameter of 0.5-1.5 µm. By changing the synthesis conditions, the vanadium oxidation state and microspheres surface morphology can be varied. The microspheres of V 2 O 5 are formed during aerobic synthesis, while V 2 O 3 microspheres are produced under an atmosphere of argon. An increase in the concentration of the initial solution leads to an increase in both size of V 2 O 5 nanoparticles and the diameters of the V 2 O 5 microspheres. Long-term storage of V 2 O 3 in air results in morphological degradation of the microspheres.
