Studies on the Thermal Decomposition Characters of Mg/KClO4 Pyrotechnic System under Static Air Atmosphere by TG and DTA

摘要：

Pure potassium perchlorate and binary mixture of magnesium and potassium perchlorate with zero oxygen balance (mass ratio of magnesium and potassium perchlorate is 41:59) were researched by using simultaneous TG-DTA under static air atmosphere, and the results show that pure potassium perchlorate has an endothermic peak at 300 corresponding ℃ g to a rhombic-cubic transition, a fusion temperature around 580℃ and decomposes at about 600 ℃, yet at 480℃ potassium perchlorate and magnesium start to react which is main solid-solid exothermic reaction and there is gas creation. Mg and air react at about 580℃, which is a exothermic reaction. The residues were analysised by XRD, and the result shows that the residues are the mixture of MgO and KCl.
