Determination of Aluminum in Organo-Aluminum Compounds by X-Ray Fluorescence.
Analytical Chemistry, 1963An x-ray fluorescence method was developed for the determination of Al in highly reactive, liquid organo-aluminum compounds over the range of 0.05 to 10%. A chromium xray target tube and a pulse height discriminator are used. (D.L.C.)

THE EFFECT OF DISHWASHING COMPOUNDS ON ALUMINUM
Canadian Journal of Research, 1941Several proprietary dishwashing compounds, in [Formula: see text] solution, were found to appreciably attack commercial aluminum and aluminum utensils. Curves are shown illustrating also the corrosive effect on commercial aluminum [Formula: see text] of [Formula: see text] aqueous mixtures, in various proportions, of the salts usually present in such ...

Impurity localization in aluminum oxide compounds
Inorganic Materials, 2011Heat-treatment products of commercial γ-Al(OH)3 (gibbsite) were characterized by X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray fluorescence spectrometry with the aim of localizing impurities in the parent material. The results suggest that at least a fraction (about half) of typical impurities in the form of readily ...

Clinical evaluation of a samarium/aluminum compound filter
Oral Surgery, Oral Medicine, Oral Pathology, 1989Rare earth compound filters, which offer reduced patient exposure during intraoral radiography, have not been clinically evaluated for their effect on diagnostic yield. This clinical study was conducted to compare the diagnostic yield of bitewing radiographs exposed with a conventional aluminum filter with matched bitewing radiographs exposed with a ...

Aluminum compounds used as adjuvants in vaccines.
Pharmaceutical research, 1990The structure of nine commercially manufactured aluminum-containing adjuvants was investigated by X-ray diffraction, infrared spectroscopy, transmission electron micrography, and energy dispersive spectrometry. Seven samples which were labeled as aluminum hydroxide were identified as boehmite, a crystalline aluminum oxyhydroxide [AlO(OH)]. However, the

Magnetic characteristics of lanthanide-aluminum compounds
Journal of the Less Common Metals, 1968Abstract Susceptibilities (χ) for α-Ce 3 Al (hexagonal) are presented for the temperature range 4 °–870 °K, and for β-Ce 3 Al (cubic), Pr3Al, Pr 2 Al and PrAl 4 , for the temperature range 4 °–300 °K. These data together with previously published results provide magnetic information for all known Ce-Al and Pr-Al compounds. Magnetization vs .

Formability of Hybrid Aluminum-Magnesium Compounds
Key Engineering Materials, 2013In the SFB 692 HALS (High-strength aluminum based lightweight materials for safety components), subproject B-3, the production of an aluminum magnesium compound by a hydrostatic co-extrusion process was investigated. The quality of these semi-finished products, especially the stability and robustness of the interface between the aluminum (AlMgSi1 ...

Formation and nitridation of vanadium-aluminum intermetallic compounds
Analytical and Bioanalytical Chemistry, 2002V(5)Al(8) and V(3)Al intermetallics have been formed by interdiffusion, by annealing of sputtered V/Al-multilayers at 700 degrees C in vacuo; sapphire (102) was used as substrate. The V/Al intermetallics were nitridated in NH(3) at 900 degrees C for 1 min by RTP (rapid thermal processing).

The inactivation of pepsin by compounds of Aluminum and Magnesium
American Journal of Digestive Diseases, 1941Aluminum hydroxide, aluminum phosphate and aluminum chloride inactivate pepsin even at a pH as low as 1.0 to 2.0. This is due in part to the inhibition of peptic digestion by aluminum ions. Magnesium trisilicate does not inactivate pepsin at such pH levels.

POTENTIOMETRIC ANALYSIS OF ALUMINUM ALKYL COMPOUNDS
1967ABSTRACT The analysis of aluminum trialkyls, of aluminum alkyl mono- and dihalides is effected by their formation of complexes with Lewis bases, in particular isoquinoline, and determining their equivalence point by potentiometric methods. The electrode system consists of two small bars of aluminum, one of which is dipped into the solution to be ...
