The thermochemical and combustion behaviour of pyrotechnic payloads based on magnesium, Teflon trademark and Viton trademark, so-called MTV is discussed. Thermochemical and FTIR-spectroscopic analysis of magnesium/Teflon trademark combustion residues indicates the intermediate formation of a Grignard-type C-Mg-F 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 xi (Mg) propor to 0.2 to xi (Mg) propor to 0.70 and declines at xi (Mg)> propor to 0.70. A tentative mechanism for the combustion process is presented. (Abstract Copyright [2002], Wiley Periodicals, Inc.)
