The exothermic decomposition reaction in the condensed phase, followed by sublimation, has been considered as the basic mechanism of ammonium perchlorate burning. The kinetic retardation or acceleration of the burning process has been connected with the change of equilibrium concentration of perchloric acid limiting the decomposition, under the influence of sublimated components of different solubilities (ammonia and perchloric acid) as well as decomposition products (water and hydrogen chloride), which shift the equilibrium state of reactions: NH4 CIO4 (s) ⇌ NH3 (s) + HCIO4 (s). The formulas obtained explain the main characteristic features of the dependence of the burning rate of ammonium perchlorate on pressure, namely, the initial growth of burning rate with pressure, the plateau or the rate drop, and the subsequent growth at high pressures. The influence of additional heat sources and heat losses on the kinetic effect of burning retardation has also been analyzed. © 1971 The Combustion Institute All rights reserved.
