Thermal Safety Study of Bistetrazolohydrazine

The thermal decomposition behavior of HBT was studied by TG-DSC thermal analysis method. The decomposition products of HBT were analyzed. TGA curves and differential thermal curves of HBT were measured in different heating rates. The activation energy and pre-exponential factor of HBT was separately calculated by Ozawa equation and Kissinger equation. Thermal decomposition Mechanism of HBT were derived by Ozawa equation and its possible mechanism function was got. The differential thermal curves of HBT prepared by different dispersants were measured and the kinetic parameters were obtained. These kinetic parameters are in good agreement. The test values of the HBT dispersed with acetone have a higher accuracy, so the activation energy calculated is more meaningful.
