Abstract

In view of contradictory opinions expressed in the literature concerning the mechanism of the thermal decomposition of barium perchlorate, additional experiments on the decomposition of barium perchlorate, chlorate, and chlorite have been performed. It is shown that neither of two previously proposed mechanisms is in accord with all the experimental data, and a modified mechanism is proposed. While the possible role of partial melting cannot be excluded completely, the suggested mechanism consists of the following solid-phase reactions:. (C 1 O4- ⇆ C 1 O3- + O, (1); C 1 O4- + O → C 1 O3- + O2, (2); C 1 O3- → C 1 O2- + O, (3); C 1 O2- → C 1 O- + O, (4); C 1 O- ⇆ C 1- + O, (5); O + O + M → O2 + M, (6)). The induction period, the discontinuity at approximately 50% decomposition, the effect of added Cl-, and the dta and tga data can all be explained using this mechanism.
