EFFECT OF PHASE CHANGE IN SOLID-SOLID REACTIONS

Abstract

The effects of phase changes, defect structure, mechanical treatment, moisture content and doping of the constituents of the potassium chlorate-sulfur system on the reactivity of the system was investigated by means of differential thermal analysis, thermoconductimetric analysis and burning rate studies. The effect of confinement during burning of the fuel mis (potassium chlorate, sulfur and sodium bicarbonate) was also investigated. It was found that the mechanism of the KClO3-S reaction is independent of the decomposition of the KClO3, but is dependent upon the lattice 'looseness' of the KClO3 and its permeability to the sulfur molecules. It was also found that previous treatment of the constituents such as mechanical and thermal treatment or the production of certain defect structures have an important effect on the stability of the system. Burning rate studies indicated that the growth of burning to detonation in the fuel mix is profoundly enhanced by a large K factor in the munition.
