SYNTHESIS AND COMBUSTION CHARACTERISTICS OF NOVEL HIGH-NITROGEN MATERIALS
RESUMO
The synthesis of high-nitrogen energetic materials has been of ongoing interest at the Los Alamos National Laboratory (LANL). We have discovered that high-nitrogen materials can offer interesting performance and sensitivity properties not accessible through conventional energetic materials. For example, some of the high-nitrogen materials developed at LANL have extremely fast burn rates and very low dependence of the burn rate on pressure. Examples of this include 3,6-bis (tetrazol-5ylamino) tetrazine (BTATz) and diaminoazotetrazine N-oxides (DAATOx) materials. In this paper, we will discuss our recent developments in our continuing efforts toward the synthesis of new highnitrogen materials that feature interesting combustion and explosives properties. In particular, we will describe the synthesis of the high-nitrogen materials dinitroazotriazole (DNAT), dinitroazoxytriazole (DNATO), and the corresponding triaminoguanidinium salts (TAGDNAT, TAGDNATO), and present chemical properties such as density, and heat of formation, as well as their sensitivity properties. Thermo-equilibrium calculations (Cheetah code) were used to predict decomposition products as well as propellant and explosives behaviors. Finally, we will present burning rate data for these new materials.
