The enthalpy of formation in the standard state for the promising novel energetic material [1,2,5]oxadiazolo[3,4-e][1,2,3,4]-tetrazine-4,6-di-N-dioxide (furazano-1,2,3,4-tetrazine-1,3-dioxide) was calculated using a theoretically calculated value of the heat of formation in the gas phase and am experimentally measured value of the heat (enthalpy) of sublimation. The theoretical calculations were performed using the G2, G3, and CBS-QB3 high-accuracy multilevel quantum chemical techniques.

Results of investigations of physicochemical processes which develop in furazanotetrazine dioxide under irradiation by a high current electron beam with an energy density varied in a range of 0.05-0.3 J/cm 2 are represented. The spectral kinetic characteristics of pulse cathodoluminescence are measured, and thresholds of the mechanical failure and explosive decomposition of samples are determined. A strong effect of the energy density of the electron beam on kinetics of the explosive transformation (induction period and duration of explosive glow) is revealed. The dimensional effect of the explosion initiation is found.
