摘要：

In order to find a solution for continuous testing of the physically varying process of pyrotechnic material decomposition with temperature change, a method is proposed based on using digital cameras and differential scanning calorimetry (DSC). A small amount of loose or compacted pyrotechnic material is placed in the crucible of a DSC system that can continuously heat and cool the sample from room temperature at a certain heating or cooling rate. Pictures are taken by a high-definition digital camera to record the physical appearance of the samples that allows monitoring the physical properties of pyrotechnic samples continuously as a function of temperature. This method is not only simple, universal and safe to operate, but also provides a new way to analyze the stability of the pyrotechnic composition.
