Decomposition, Pyrolysis, and Deflagration of Pure and Isomorphously Doped Ammonium Perchlorate

Abstract

A perchlorate (AP) is the oxidizer and principal ingredient in most composite solid propellants and its behavior in the cumbustion zone affects the overall combustion characteristics of the propellant. Because the written word can only partially describe this behavior, a 16 mm film has been prepared in which scanning electron micrographs (SEM), cinephotomicrography, graphs, charts, and plots are used to describe the phase changes orthorhombic to cubic and cubic to orthorhombic; the sublimation, isothermal decomposition, pyrolysis, and selfdeflagration of pure AP; and the self-deflagration of AP crystals isomorphously doped with K , Cr207~ and Mn04~ ions.
