Ignition and Combustion Mechanism of MTV

It is generally assumed that the PIR yields a meta-stable species, M- AX, constituted from both metallic fuel, M, and oxidant, AX, according to the general Eqs. (6.1) and (6.2)  

The onset temperature of the pre-ignition reaction, TpiR, is usually independent of the melting or decomposition temperature of the oxidizer but related to the thermodynamic melting temperature, Tmeit of the metal  

For low melting metals such as Al, Mg and Zn, we find that a 0.75 0.05 however, with refractory fuels such as Ti and Zr, a 0.45 0.05. Table 6.1 Hsts Tpif. and onset temperature for steady-state combustion of a number of M/PTFE (polytetrafluoroethylene) pyrolants.

The formation of 1 by Knochel reaction [22] from trifluoromethylphenylbromide with isopropylmagnesium(II) chloride in solutions 1M can lead to a rapid increase in temperature and pressure. Hence, this reaction must be diluted down to 0.6 M to avoid catastrophic outcome [23].
