Abstract
Dependences of the brightness temperature of the detonation front and detonation products on detonation pressure were determined by the pyrometric method in the range of 0.7-9.4 GPa. The pressure was varied by changing the initial density of the emulsion explosive in the range 0.43-1.2 g/cm3. Polymer microballoons were used as sensitizer. The dependence of the brightness temperature in the Chapman-Jouguet plane on detonation pressure is found to be nonmonotonic. In the investigated pressure range, the measured temperature values changed from 2250 to 1830 K. A comparative analysis of the application of polymer and glass microballoons as sensitizers is performed. The obtained experimental data are compared with the calculation available in the literature.
