Summary: | As the only solid detonation product of CHNO negative oxygen balance explosive, the condensed carbon plays an important role in the energy-releasing and working capability by coagulation and phase transition. But the process of condensed carbon transformation has always been controversial because the detonation is so fast and the carbon phase is so complex (amorphous phase, graphite phase, diamond phase, liquid phase, etc.), that spatial and temporal resolution of existing test techniques is difficult to meet the requirements of quantitative analysis. If we can accurately understand the phase transition and coagulation process of carbon condensation during detonation, we can provide effective reference data for the accurate evaluation of explosive energy release process and damage effect, rational design of formula, and accurate correction of non-ideal explosive detonation model.
