Summary:Title screen
Isotherms of the sorption of water vapor by aluminum powders of different grades (ASD-4, ASD‑6, PA-2, PA-4, PAD-2, PAD-4, PAP-1, and PAP-2) are determined experimentally. The sorption of water vapor with ASD, PA, PAD powders begins at humidities above 80%. The kinetics of the chemical reaction between water vapor and aluminum is characterized by an induction period whose duration depends on the grade of aluminum and the relative humidity of the air. A mechanism is proposed for the reaction between water vapor and aluminum powders, in which an important role is played by atomic hydrogen that is released in the main reaction and participates in a chemical reaction that destroys the oxide-hydroxide protective film on the granules of aluminum powders. The hygroscopicity of PAP powders is determined from the absorption of water vapor by the fatty film, and not by the aluminum itself
