摘要: The thermal decomposition of ammonium perchlorate (AP) with Al and Zn metallic particles was studied at different heating rates in dry air atmosphere the combustion behavior AP/Al/Zn propellant evaluated. exothermic reaction kinetics by differential analysis (DTA) non-isothermal conditions compare pure AP AP/aluminum analyzed same experimental conditions. Arrhenius parameters were estimated according to Ozawa Kissinger methods. calculated activation energies for low high temperature reactions 91 229 kJ/mol AP, 90 112 80 wt% AP/20 particles. When zinc incorporated, energy 56 determined only peak observed AP/10 44 78.4 AP/19.6 Al/2 composition.
