Isothermal decomposition and mechanism of N-guanylurea dinitramide

The isothermal decomposition of a new material with high energy, namely N-guanylurea dinitramide (FOX-12), was studied by a self-established isothermal decomposition gas metering device. The gas pressure versus time curves of the isothermal decomposition of FOX-12 were obtained at temperature intervals within 120 °C and 170 °C. An extremely long lag phase and acceleration period were found in the decomposition process of FOX-12. The kinetic...
