Simultaneous thermal analysis techniques for characterization of materials has become widespread, with increased availability of instrumentation for such analyses. EG G Mound has the capability to do simultaneous thermogravimetry/differential scanning calorimetry (TG/DSC) to 825{degree}C, simultaneous thermogravimetry/mass spectrometry (TG/MS) to 1000{degree}C, and high temperature thermogravimetry/differential thermal analysis (TG/DTA) to 2400{degree}C. Advantages of these simultaneous techniques include the exact correlation of TG weight loss data with observed enthalpic transitions and with evolved gas analysis. These thermal analysis techniques have proven to be very useful in the characterization and study of reactions of energetic materials. In this study, several secondary explosives have been examined by TG/DSC to determine weight losses during melting and decomposition, and by TG/MS to identify the decomposition products. Reactions of two pyrotechnic blends were studied by TG/DTA under varying analysis conditions. 5 refs., 3 figs., 3 tabs.
