Effect of Initial Temperature and Pressure on the Burning Rate of AGAT/AN Mixtures

The combustion characteristics of aminoguanidinium 5,5′-azobis-1H-tetrazolate (AGAT)/ammonium nitrate (AN)-based gas generating agents were studied by using a temperature-controlled chimney-type strand burner. Controlling the initial temperature at 243, 298, or 343 K, the mass burning rates of AGAT/AN = 50/50 were measured and the temperature sensitivities were deduced. The effects of CuO and MnO2 on temperature sensitivity were studied. The temperature sensitivity equation as a function of pressure and initial temperature was also determined.
