The thermochemical and combustion behaviour of pyrotechnic payloads based on magnesium, Teflon ® and Viton ® , so‐called MTV is discussed. Thermochemical and FTIR‐spectroscopic analysis of magnesium/Teflon ® combustion residues indicates the intermediate formation of a Grignard‐type CMgF compound in the condensed phase as part of a preignition reaction (PIR). The PIR is mainly responsible for the observed burning rate which rises exponentially with rising magnesium weight fractions from ξ(Mg)∼0.2 to ξ(Mg)∼0.70 and declines at ξ(Mg)>∼0.70. A tentative mechanism for the combustion process is presented.
