Abstract
Regularities of the interaction of widely dispersed industrial powders and electroexplosive aluminum nanopowder with nitrogen under atmospheric pressure in a linearly rising temperature and isothermal conditions have been investigated. The effect of the powder's dispersion and composition, and the structure of the oxide shell and metal core of the aluminum particles on the temperature range of reaction and its kinetic parameters is shown. The relationship between the process of dehydration of hydroxides that are part of the superficial oxide shell of Al particles and the initial temperature of interaction between the powders and nitrogen was investigated. It is shown that the staged nature of weight gain for powders in a nitrogen atmosphere that is observed under conditions of linear heating results from a change in the macrokinetic regime, due to the effect of the Al nitride layer.
