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.

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.

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 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]}.
