Adsorption interaction between Al–5% Pb alloy and water

The adsorption and structural features of Al–5% Pb alloy powder before and after reacting with water are analyzed. Results from studying the morphology and phase composition of the oxidation products are presented, and the specific surface area and porosity of the powders are calculated. It is shown experimentally that water treatment of Al–5% Pb alloy powder even at room temperature leads to the formation of new phases and affects the powder’s morphology. It is established that a major role in the properties of the watertreated powders is played by nanopores that form between crystallites on a particle’s surface during waterinduced oxidation and subsequent thermal dehydration.
