Synthesis of Insensitive 5,5′-Azotetrazolate Salts

Salts of 5,5′-azotetrazolate with 5-aminotetrazole and 2,4,6-triamino-s-triazine cations were synthesized as potential ingredients for gun propellants. These salts were characterized by nuclear magnetic resonance (NMR) and infrared spectroscopy. Thermal properties were studied by differential scanning calorimetry (DSC). Their reactions to mechanical stimuli were also determined by small-scale sensitivity testing, small-scale shock reactivity testing, and small-scale internal blast testing.
