Peculiarities of interaction of small metal particles with reagents

Abstract

Using as an example a chemical reactions occurring under relatively soft conditions, it is shown, that temperature inside of the ultrafine particles during its oxidation is essential higher than that in reacting layer. The temperature difference may come up to hundreds degree. This leads to change of the reaction kinetics and stabilization of the reaction finished products, which are not a typical ones for the same processes with normal size (not ultrafine) powders. Obtained results may be used for analysis of the powders reactivity.
