Аннотация: The electrosurface properties of aluminum oxide particles prepared by shock—wave loading of aluminum powder in an oxygen-containing atmosphere and the aggregation stability of its aqueous dispersions are studied by the macroelectrophoresis method, potentiometric titration, and photometry. The enhanced stability of the dispersions in acid media and in the vicinity of the isoelectric point compared to that in alkaline media is explained by the effect of the structural component of the disjoining pressure, which appears due to the predominant hydration of the cationic forms of aluminum that are present on the surface of dispersed phase particles.
