For the mixture of KMn O4+RP+Teflon，as seen in Tab.3，critical ignition temperature is 242.6℃，which is less than the critical ignition temperature of RP itself，indicating that the mixture of KMn O4+RP+Teflon was more reactive than RP itself.On the other hand，by replacing KMn O4with Mn O2and KNO3powder，the thermal sensitivity of the mixture decreases and ignition temperature of Mn O2+RP+Teflon and KNO3+RP+Teflon systems reach to 353.0℃and378.4℃.Finally，the replacement of KMn O4with Fe2O3and Ba（NO3）2raises the thermal stability of the mixture and ignition shifts toward the higher temperature up to 406.1℃and 421.1℃.Ba（NO3）2+RP+Teflon mixture with ignition temperature about 178℃higher than that most reactive mixture has the highest stability among the investigated mixtures.
