Thermal and x-ray diffraction (XRD) analyses have been used in studying reactions of pyrotechnic blends. The reactions were performed in the thermal analysis instrument, and the products were analyzed by XRD. Two pyrotechnic blends -- B/CaCrO{sub 4} and Ti/KClO{sub 4} -- were studied in different reaction environments, including: air, high purity argon, and high vacuum. Thermogravimetric Analysis/Differential Thermal Analysis (TGA/DTA) of a 20/80 wt % B/CaCrO{sub 4} blend in air showed a weight gain (TGA) and an increase in the reaction enthalpy (DTA), compared to reactions in a vacuum or high purity argon. Analyses (TGA/DTA) of a 33/67 wt % Ti/KClO{sub 4} blend in air showed an additional DTA exotherm, following the main reaction peak, accompanied by a small weight gain. Neither was observed in high purity argon or in a vacuum. Reaction products from both blends were determined by XRD. 4 refs., 2 figs., 1 tab.
