Abstract

Azo-Tetrazolate salts and their derivatives have identical negatively conjugated nitrogen rings and two varied positively charged cations. The varied cations are Guanidinium, Aminoguanidinium, Diaminoguanidinium, Triaminoguanidinium and Ammonium. Azo-Tetrazolate salts and their derivatives were synthesized and fully characterized by multinuclear spectroscopy (NMR) and Fourier Transform Infrared Spectroscopy (FTIR). The thermal behavior and decomposition kinetics of Guanidinium Azo-Tetrazolate (GAT), Aminoguanidinium Azo-Tetrazolate monohydrate (AGATH), Diaminoguanidinium Azo-Tetrazolate (DAGAT), Triaminoguanidinium Azo-Tetrazolate (TAGAT)and Ammonium Azo-Tetrazolate (AZT), were investigated by Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) techniques. The kinetic and thermodynamic parameters of these energetic materials were calculated non-isothermally by DSC instrument, under various heating rates (2, 5, 10, 15 °C/min) Differential Scanning Calorimetry (DSC) was performed to investigate the compatibility and the interaction between the energetic materials. Different percentages (10%, 15%, 20%) of Azo-Tetrazolate materials by mass were mixed with Crosslinkinked HTPB and investigated by DSC and TGA to indicate the effect of additives, under Oxygen and heat rate 5°C/min. Equal amount of two different energetic materials were used to form 20 % by weight of the mixture and was investigated by DSC and TGA to indicate the effect of additives. The kinetic and thermodynamic parameters of the 20 % of each energetic material mixtures were investigated non-isothermally by DSC under various heating rates (5, 10,15 °C/min) following the ASTM E 698 standard.
