Suitability of nitrogen rich compounds for gun propellant formulations

This paper reports the suitability of a novel nitrogen rich compound, guanidinium-5-aminotetrazolate for RDX-based high-energy gun propellant formulations in respect of flame temperature as well as the burning rate characteristics. It has been found that the partial replacement of RDX with guanidinium-5-amino tetrazolate at the rate of five parts decreases the flame temperature of the propellant by about 120 K without adversely affecting the burning rate characteristics, i.e. linear rate of burning co-efficient and pressure exponent.
