　　In our work we will interest in the study of self-accelerating decompositiontemperature TSADTof pyrotechnic compounds such as black powder （75%KNO310%C and15%S）, and another mixture which contains （75%KClO415%CrCl3and10%S）. We willdiscuss the application of the DSC traces after advanced kinetic analysis for thedetermination of the Time to Maximum Rate under adiabatic conditions （TMRad）. In thiswork, attention will be focused on the applicability of AKTS-thermo kinetics software onthe determinati...
