These systems consist of metal (e.g. aluminum) and oxidizer nanopowders. The MIC formulations are based on intimate mixing of reactants on the nanometer length scale. As the specific surface area increases, the number of contact points between the reactants also increases and therefore the reaction rate increases
-
the reaction rate depends on other factors, including particle size distribution and degree of intermixing
-
Reaction rates between nanosize aluminum and metal oxides can be significantly greater than those observed with traditional micron-size thermite powders.
