Abstract

The feasibility of obtaining highly dispersed aluminum oxide powders by the electrical explosion of aluminum conductors in an inert gas atmosphere and the subsequent oxidation of aluminum particles by water prior to their contact with air is demonstrated. For a specific surface area of the initial aluminum powder of 6.5$m^2$/g, the corresponding specific surface area of the resultant aluminum oxide nanopowder was as large as 300$m^2$/g.
