Abstrakt: Thermal analyses of raw components are necessary to understand the behavior of pyrotechnic compositions they are incorporated in. Ternary compositions containing strontium peroxide, magnesium, and 2, 4‐dinitroanisole (DNAN) are studied thermally using TGA and DSC. Activation energies are given for the components using three different methods. Thermal behavior of strontium peroxide is focused on as little scientific literature exists about it: heat capacity is measured, and a thermal evolution model is given. Effects of magnesium particles size are also studied. The results obtained show that the presence of DNAN decreases activation energies of all reactions within the ternary compositions. Decreasing magnesium granulometry only decreases the activation energy of magnesium oxidation, but does not play a role in other reactions. [ABSTRACT FROM AUTHOR]
