ABSTRACT

The experimental and theoretical study of ignition and combustion particles of crystalline boron in chlorine are presented. The temperatures of the ignition of the single boron particles is within the range 700−1300 K. The process of ignition is well described by the heat theory of ignition. The analysis of calculated and experimental data has shown that the crisisless regime is well possible at certain external conditions; this results from the low activation energy of the reaction of boron with chlorine. The combustion process of single boron particles with diameters of more than 20 μm is heterogeneous under the diffusion regime. The proposed combustion model which takes into account the formation of BCL and BCL2 is in good agreement with the experimental results. The comparison of the characteristics of ignition and combustion of boron in chlorine and oxygen-containing media shows that the boron ignition temperature in chlorine is much lower than in oxygen-containing media; however, the rates of combustion are lower.
