Science, 1976
Balloons and U-2 aircraft were used to collect micrometer-sized stratospheric aerosols. It was discovered that for the past 6 years at least, aluminum oxide spheres have been the major stratospheric particulate in the size range 3 to 8 micrometers. The most probable source of the spheres is the exhaust from solid-fuel rockets.

Journal of the American Ceramic Society, 1993
Unreinforced AlN/Al ceramic/metal composites were produced by the directed oxidation of molten Al alloys in nitrogen. The microstructures of these composites were compared with those of previously studied Al 2 O 3 /Al composites.

Transactions of the American Institute of Electrical Engineers, 1932
INTEREST in oxid coatings on aluminum began with the discovery of the metal about 100 years ago, for the chemical attraction of aluminum for oxygen is one of the most important characteristics of the metal. At various times in the history of aluminum, attention, from the scientific standpoint or from the commercial point of view, has been focused on ...

Adsorption study of aluminum oxide monohydrate and ?-aluminum oxide
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19601. The thermal conversion of boehmite toγ-alumina was studied by an adsorption method. Detailed structural characteristics of five samples with different H2O contents were determined. 2. The absolute isotherms for the adsorption of argon and nitrogen at −195° and n-C6H14 and C6H6 at 20° were calculated.

Aluminum–aluminum oxide stylus arm
The Journal of the Acoustical Society of America, 1985An improved stylus assembly for a phonograph cartridge is provided. The assembly includes an arm having a jeweled stylus attached to one end thereof. The arm is formed of a hollow aluminum tube which has been anodized so as to form an aluminum oxide skin about the outer surface thereof.

Wetting of aluminum oxide by liquid aluminum
International Journal of High Technology Ceramics, 1986Abstract The wetting of aluminum oxide by liquid aluminum can be improved considerably by a change of the interfacial energy between the oxide and the metal. The presence of an extremely thin carbon layer at the interface between the oxide and the metal results in a significant decrease of the contact angle.

Oxidation of Aluminum in Ozonated Water
Physica Scripta, 2004The oxidation of silicon and copper alloyed aluminum thin films in ozonated water was studied. Experiments were performed in a wet bench at different temperatures. The oxidation was studied mainly by optical methods and sheet resistance measurements. The films oxidized only slightly at 5 and 15°C. At 25 and 35°C an oxide film formed faster.

Aluminum Ion Diffusion in Aluminum Oxide
The Journal of Chemical Physics, 1962The self-diffusion coefficient of aluminum has been determined in polycrystalline aluminum oxide over the range 1670° to 1905°C. Diffusion couples were employed using aluminum-26 in oxide form as a radioactive tracer. In the temperature range studied, experimental data can be represented by D = 28 exp {—[(114 000±15 000)/RT]}.

Oxidation dynamics of aluminum nanorods
Applied Physics Letters, 2013Aluminum nanorods (Al-NRs) are promising fuels for pyrotechnics due to the high contact areas with oxidizers, but their oxidation mechanisms are largely unknown. Here, reactive molecular dynamics simulations are performed to study thermally initiated burning of oxide-coated Al-NRs with different diameters (D = 26, 36, and 46 nm) in oxygen environment ...

Ferrocyanide adsorption on aluminum oxides
Journal of Colloid and Interface Science, 2004Ferrocyanide (Fe(CN)6(4-)) adsorption onto gamma-alumina ( gamma-Al2O3(s) ) and gibbsite (Al(OH)3(s)) was investigated over a wide pH range and at various solid loadings. Batch experiments were performed using 100-ml solutions (I = 0.01 M NaCl) dosed with 1.0 mgl(-1) Fe(CN)6(4-) as CN.
