Abstract

To obtain a better understanding of the thermal decomposition properties of energetic compositions of guanidine nitrate (GN) and azodicarbonamide (ADCA), differential scanning calorimetry (DSC) and thermogravimetry-differential thermal analysis connected with infrared spectroscopy (TG-DTA-IR) and with mass spectrometry (TG-DTA-MS) were carried out, and the onset temperature, heat of decomposition and evolved gas were determined. Furthermore, residue of thermal decomposition at various conditions was identified with Fourier transformation infrared spectroscopy (FT-IR) analysis. Experimental results suggested that the thermal decomposition of GN proceeded with the balance between the rates of vaporization and decomposition above a certain temperature and evolved gas products of thermal decomposition of GN/ADCA compositions are influenced by the mixing ratio.
