Abstract

In view of the great practical utility of aluminum–rare earth metal (REM) powders as adsorbents and catalyst supports, the dispersion composition and morphology of Al–3%Y alloy powder particles obtained by various methods (gas plasma recondensation, nitrogen sputtering) were studied by low-temperature nitrogen adsorption, scanning electron microscopy, XRD, etc. The phase composition of the powders was determined, and the amount of active aluminum was calculated. The nitrogen adsorption on the powder surface was studied experimentally at–196°С at relative pressures of Р/Рs = 10–3–0.999. The specific surface areas of the powders were determined.
