The influence of inorganic substances on oxidation characteristics of nanopowders

Solid-phase processes at heating (20-1000/spl deg/C) in the air of aluminium and tungsten nanopowders, produced by electrical explosion of conductors were explored. It was shown the influence of inorganic substances (MnO/sub 2/, CuSO/sub 4//spl middot/5H/sub 2/O) on oxidation characteristics of nanopowders: initiation of oxidation temperature, oxidation rate, maximum temperature of exothermic effect by means of differential thermal analysis and thermogravimetry.
