Abstract

We have dealt in detail with the decomposition of ammonium perchlorate in the presence of different amounts of pure, and doped with foreign ions, zinc oxide. The rate and extent of the reaction were markedly increased by the addition of zinc oxide, and the temperature of explosion of ammonium perchlorate was lowered with about 200°C. Doping of zinc oxide with lithium and aluminium oxide, resp., considerably influenced the decomposition, first of all the values for induction periods and rate constants. From the temperature dependence of the rate constants and the times required until explosion occurs, about 32 kcal activation energy was estimated, that is, both the decomposition catalyzed by zinc oxide and the explosion iniciated by zinc oxide take place according to an electron transfer mechanism. The role of zinc oxide is interpreted so that it promotes the melting of ammonium perchlorate.
