Abstract
Pycnometric method, powder X-ray diffraction analysis, and IR spectroscopy were used to study the fundamental aspects of how the density of energy-rich compound furazano[3,4-e]tetrazine-4,6-dioxide varies during its prolonged storage. It was shown that the density grows during the first stage with length of up to 14 days due to the recrystallization. In further storage during eight years, the density gradually falls due to the buildup of stresses in the crystal lattice, created by thermal decomposition products. The degree of decomposition at 22°C during 8 years, evaluated by extrapolation of the Arrhenius dependence, is 0.24%. The observed decrease in the density is attributed to the anomalously weak hampering effect of the crystal lattice.
