The investigation of the aluminum nitride formation during the aluminum nanopowder combustion in air
The phase formation sequences, intermediate and final products of aluminum the nanopowder combustion are studied. It is found, that the main combustion product is aluminum nitride. In the combustion of aluminum nanopowder, aluminum γ-oxide is the first to form, and aluminum nitride is formed next. The formation of aluminum probably occurs by successive displacement of oxygen by nitrogen from the aluminum oxide. The use of sliding (incident at a small angle to the surface) synchrotron radiation made it possible to determine with high accuracy (in time) the sequence of stages of formation of crystalline products during combustion of the aluminum nanopowder.
