Thermal behavior of metallic fuel pyrotechnics of Al, Mg and alloy of Al–Mg: a review

Pyrotechnics are among the energetic materials that have wide applications in various military and civilian fields. Thermal behavior and thermal stability are the very important properties of pyrotechnics. The thermal stability of a pyrotechnic shows the scope of application as well as safety. Thermal analysis methods such as TGA, DTA, and DSC are used to obtain information on the thermal behavior and thermal stability of pyrotechnics. The first review in the field of thermal analysis of pyrotechnics was published by P.G. LAYE and E.L. CHARSLEY in Thermochimica Acta Journal in 1987. The results of thermal analysis of pyrotechnics containing molybdenum trioxide, lead oxides, nitrates, perchlorates and chlorates, dichromates and chromates have been reviewed and discussed in mentioned paper. Over time, investigating the thermal behavior of pyrotechnics can be useful for scientists in this scientific field. It is possible to consider various divisions for pyrotechnics based on the type of fuel, type of oxidizer, etc. In the present paper, the results of the thermal behavior of pyrotechnics are reviewed and discussed based on the type of metallic fuel including the common metals aluminum, magnesium, and Al–Mg alloy (magnalium).
