Coagulation of the Ionized Combustion Products in a Dust Flame of Aluminum Particles
Journal of Chemistry, Volume 2019, Issue 1, 2019., 2019 The addition‐agent effect of atoms of alkali metals (K, Na, Li, and Cs) and halogens (Cl and I) introduced into the combustion zone of a dust flame of aluminum particles on the average size of Al2O3 nanoparticles is studied. A physical model of coagulation of a monodisperse aerosol is proposed.

Journal of Nanomaterials, Volume 2015, Issue 1, 2015., 2015 High crystalline Al‐doped ZnO (AZO) nanopowders were prepared by in‐flight treatment of ZnO and Al2O3 in Radio‐Frequency (RF) thermal plasma. Micron‐sized (~1 μm) ZnO and Al2O3 powders were mixed at Al/Zn ratios of 3.3 and 6.7 at.% and then injected into the RF thermal plasma torch along the centerline at a feeding rate of 6.6 g/min.

Selective Growth of α‐Al2O3 Nanowires and Nanobelts
Journal of Nanomaterials, Volume 2008, Issue 1, 2008., 2008 We report the selective growth of α‐Al2O3 nanowires and nanobelts via a catalyst‐free chemical vapor deposition process under ambient pressure. By controlling the flow rates of the carrier gas, high‐yield production of uniform alumina nanowires with diameter distribution (100 nm–200 nm) was achieved at a high growth rate over 200 μm/hour.

The onset of asymmetric combustion of aluminum particles
, 2019 Combustion of an aluminum droplet in an oxidizer atmosphere is known to proceed in several stages. Ignition is followed by a first combustion stage in which the droplet is surrounded by a spherical diffusion flame, but this flame and the conditions at ...

Verdampfungsuntersuchungen am System Al₂O₃-SiO2 mit einem HF-Plasmabrenner
, 1975 Es wurde die Verdampfung von Feststoffen aus dem System Al₂O₃-SiO₂ in einem strömenden N₂-Plasma untersucht. Die Untersuchungsmethode gestattet die Registrierung verdampfender Komponenten im Dampfraum als Funktion der Verdampfungszeit.

About suboxide form of oxygen in steels and cast irons
, 2018 Исследованы химические соединения кислорода в чугунах и сталях с привлечением петрографического, рентгеноспектрального и других методов анализа. Установлено, что в сталях и чугунах кислород образует не только высшие окcиды, но и низшие — субокислы (AlO ...
