Abstract
A differential thermal analyzer was used to analyse the thermal decomposition properties of samples mixed barium nitrate with 2 percent of CuO, Cu2O, Fe2O3, Fe3O4, CoO, NiO, SnO2, PbO, and MnO2 respectively. The samples were then made into firecrackers and tested on its displaying effect and mechanic sensitivity. The results show that the thermal decomposition temperature of barium nitrate added with Cu2O decreases by 45°C. Besides, the explosive sound ratio of CoO increases to 85% and its paper scrap ratio reaches to 65%. The mechanic sensitivity of all the samples increases slightly.
