A study was made of the thermal decomposition of perchlorate of ammonium PA at 214 to 470C by the gravimetric method in an air atmosphere. The following values of the energies of activation of the decomposition were determined orthorhombic form, E 40 kcalmole cubic form, E 24 to 28 kcal mole and residue from low-temperature reaction E 36 to 39 kcalmole. A study was made of the influence of oxides, chlorides, carbonates, and oxalates of a number of metals on the thermal decomposition of PA. It was shown that the compounds of manganese and cobalt lead to complete decomposition of the PA at a temperature below 240C. The compounds of iron, nickel, and chromium lead to complete decomposition of PA at 270 to 280C. At the same temperature, the maximum rate of decomposition of PA with additives of the compounds of Cu, Mn, Co, as well as ZnO is greater than the maximum decomposition rate of the pure PA the maximum decomposition rate of mixtures of PA with compounds of iron, nickel II, chromium, as well as V2O5 is less than for pure PA. The activity of additives of the same element decreases in the following order carbonate oxalate, oxide, and chloride.
