| Izvleček: | Title screen Iron, aluminum, copper and tungsten nanopowders were exposed to microwave radiation. Thermochemical parameters of the irradiated metal powders were determined by the method of thermal analysis at the heating in air. The relationship between the structure of the protective shell on the surface of particles and changes in the thermochemical properties of metal powders after exposure to microwave radiation has been determined. The structure of the oxide-hydroxide shell of metal nanopowders determines the patterns of changes in their thermochemical properties due to exposure to high-energy radiation: The properties of nanopowders with a uniform shell (Al, W) change quasi-monotonically, and those of nanopowders with a layered shell (Fe, Cu) change quasi-periodically. Modification of dispersed metals using microwave radiation makes it possible to impart new functional properties to metal nanopowders without introducing chemical impurities by storing energy and changing the structure of the passivating shell. An additional exothermic effect associated with the release of stored energy in irradiated metal powders will contribute to an increase in the yield of ceramic materials in the process of inorganic synthesis by combustion, as well as in the processes of sintering, oxidation and combustion Текстовый файл AM_Agreement |
