Surface sensitive x-ray photoelectron spectroscopy (XPS) and x-ray induced Auger electron spectroscopy (XAES) were used to analyze surface changes in Fe/KClO/sub 4/, TiH/sub 0/ /sub 65//KClO/sub 4/ and Al foils in KClO/sub 4/ during accelerated aging at 60 and 120/sup 0/C. The result shows a 0.02% Cl/sup -/ formation per day in Fe/KClO/sub 4/ and TiH/sub 0/ /sub 65//KC 1O/sub 4/ powders aged at 120/sup 0/C for less than or equal to 145 days. No KClO/sub 4/ decomposition was observed under the similar aging conditions in KClO/sub 4/ samples without pyrotechnic fuels. Titanium oxide to KClO/sub 4/ signal ratio in a pressed disk of TiH/sub 0/ /sub 65//KClO/sub 4/ was found to be lower than that of the powdered samples. Carbon impurities were noted in all powders, especially strong in metal (or subhydride) containing specimens; carbon impurities were slightly removed from the subhydride during aging.
