详细
The adsorption properties of an ASD-4 aluminum powder and the powder modified with copper formate in different concentrations of 1, 2, 3, and 5 wt % were studied using the low-temperature adsorption of nitrogen at 78 K. The structural properties as morphology and phase composition of the interaction products were studied; the specific surface area and porosity were evaluated. It was shown that the adsorption characteristics of the powders modified with 1 and 2 wt % copper formate remained almost unchanged, which is of interest for creating a protective layer on the surface of the aluminum particles without significantly changing its structure-forming properties. The introduction of the modifier at a concentration of 3 and 5 wt % significantly affected the adsorption characteristics of the interaction products. For example, the specific surface of the ASD-4 + 3% Cu powder amounted to 12 m2/g, while that of the ASD-4 + 5% Cu achieved 19 m2/g, whereas the specific surface of the initial ASD-4 powder was only 0.7728 m2/g.
