Abstract :
The aim of the paper is to discuss about the reacting powder materials. The rates of reaction processes in powders capable to nanostructures formation are higher then rates in powders with large particles. Reduction of the initial sizes of particles at preservation of all other parameters in a powder mixture can cause to change of mechano-chemical transformations regime. In case of powders with the size of particles 5 microns in a layer are observed the fronts of burning going towards each other both causing warming up and chemical reaction in the next layers.
