Results of DTA-TG investigation and chemical analysis of electro-exploded aluminum nanopowders coated and/or passivated with the reactive reagents: nitrocellulose (NC), oleic (C17H33COOH) and stearic (C17H35COOH) acids, amorphous boron and air (for a comparison) are discussed. Surface protection of aluminum nanopowders by coatings of different origin results in significant advantages in the energetic properties of the powders. Aluminum nanopowders with a protecting surface show increased stability to oxidation during storage period.
