The thermodynamic characteristics of combustion processes of a gas-generating composition based on ammonium perchlorate have been investigated. Polyethylene was chosen as a fuel, the choice in favor of this component is due to the fact that ammonium perchlorate readily interacts with polyethylene, and this fuel contributes to the rapid decomposition of ammonium perchlorate. The optimal composition of the mixture was found. It has been established that the highest efficiency and specific gas production are observed in the area of stoichiometric ratio of the initial components of gas generator compositions. The influence of the oxidizing agent ammonium perchlorate on the energy release of composite energetic materials, the thermal decomposition of ammonium perchlorate and ammonium perchlorate with polyethylene was studied by thermogravimetry and differential scanning calorimetry. In research for simultaneous thermal analysis of the ammonium perchlorate samples and the mixture of ammonium perchlorate with polyethylene (the portion of mixture was 8.6 mg, pure ammonium perchlorate was 10 mg, and the heating rate was 10°C / min.) was found that at temperatures around 514 K, an endothermic peak is observed corresponding to a polymorphic transition in the crystal structure of ammonium perchlorate, in both cases the peaks coincide. At a temperature of about 645.3 K, an exothermic peak can be observed, at which the oxidation of polyethylene occurs with a large release of energy. The peak at 702.2 K corresponds to the decomposition of ammonium perchlorate. The developed gas generator composition based on ammonium perchlorate can be used for open pit mining for splitting block stone in a gentle mode or breaking hard mineral rocks. This composition is safe from an environmental point of view, there are no toxic gases such as carbon monoxide and nitrogen oxides in the products.
