摘要：

Optical and electron microscopy, calorimetry, IR spectroscopy, and XRD analysis were used to study the e. polymorphous transition in polycrystalline hexanitrohexaazaisowurtzitane. The kinetics of the process is extremely complex due to the intrinsic morphological features and defects in individual crystals in the polycrystalline sample. A limiting phenomenon, which manifests itself in a sharp slowdown of the process at a critical temperature, was revealed. The polymorphous transformation is triggered by dehydration, the removal of the residual water from the crystal. It was demonstrated that dislocations play an important role in the process under study.
