The article presents the results of a thermodynamic study of the component content influence and their physical and chemical properties on the regulation of the main energy characteristics and combustion product characteristics of thermite systems based on calcium iodate containing Al, B and Ti. The adiabatic combustion temperature, enthalpy of combustion products, specific impulse, exhaust velocity of combustion products, mass fraction of condensed phases, content of gaseous and condensed combustion products are determined. The influence of the metal oxide/metal fuel content in the thermite system composition on the main energy characteristics was assessed. Based on a comparison of the calculation results of the thermite systems thermodynamic and thermophysical characteristics, it seems possible to divide the studied thermite systems into 3 functional groups according to their application. Taking into account the ratio of components, these can be: 1) thermite systems for welding processes and 2) thermite systems for perforating, cutting metal structures (CaI2O6/Al and CaI2O6/Ti); 3) thermite systems as a component of energy compositions capable to inactivate harmful aerosol spores and bacteria (CaI2O6/B), since due to the low combustion temperature of CaI2O6/B, a longer burning time of such systems leads to a gradual release of iodine.
Keywords: thermite system, adiabatic combustion temperature, specific impulse, condensed combustion products, thermodynamic calculation.
