The thermochemical properties of high-temperature pyrolants were studied. Two reactive oxidizers, potassium nitrate (KNO3) and potassium perchlorate (KClO4), and two highly energetic fuels, boron (B) and zirconium (Zr), were considered. The combustion temperatures and thermochemical parameters of B/KNO3, Zr/KNO3, B/KClO4, and Zr/KClO4 pyrotechnic mixtures were investigated via thermochemical calculations using a modified dedicated calculation program package that enables estimation of the presence and concentrations of chemical compounds in condensed (solid or liquid) phases in the combustion products. The relevancy between heat generation and the quantity of gaseous and condensed products was calculated. In addition, changes in the thermochemical parameters of the pyrotechnic mixtures on increasing the combustion pressure from 0.4 to 4.0 MPa were examined. The use of zirconium led to remarkably higher combustion product temperatures compared with other metallic fuels.
