monohydrate) has recently been considered for use as a low-smoke pyrotechnic
fuel. There is relatively little information available in the literature concerning
the thermal properties of BTAw or its precursors. In the present work, various
thermoanalytical experiments were performed on BTAw and BTA (bis-(1(2)H-tetrazol-5yl)-amine)
in an effort to better characterize the thermal stability and decomposition
of these compounds.
Variable heating rate studies were carried
out on BTAw samples in a helium atmosphere using DSC and TG. Two steps were
seen in the results: dehydration followed by decomposition. Kinetic parameters
were determined for both of these steps using a number of methods. Experiments
using simultaneous TG-DTA coupled with FTIR and MS were performed on BTAw
in both helium and dry and CO2 free air atmospheres,
and evolved gas analysis was used to determine the gaseous decomposition products.
The thermal stability of BTAw and BTA was examined using accelerating rate
