The stability of the G-16 pyrotechnic primer mixture of antimony sulfide, calcium silicide, and potassium chlorate was studied at temperatures up to 200/sup 0/C in sealed and open environments. Data have shown that this mixture is stable in open environments at 200/sup 0/C for up to 48 hours. However, in sealed, limited volume environments, the mixture completely decomposes within 24 hours at 200/sup 0/C. In sealed environments, the mixture shows stability with copper present. Both functional testing and chemical analysis were used to evaluate the primer composition after temperature exposure. The degree of degradation of the mixture was determined from the concentration of final reaction products (sulfate and chloride ions), using ion chromatography. When copper was present, the intermediate reaction products were scavenged by the copper, and the degradation was reduced. The role of copper in the reaction was verified with differential scanning calorimetry and surface analysis. 3 refs., 9 figs., 2 tabs.
