Boron Combustion Product Chemistry

Abstract

This study comprises an experimental investigation of the chemistry of boron combustion products with particular emphasis on the phenomena preceding and accompanying nucleation in expanding flows. Supersonic (Mach number =3 ) jets of the burnt gases from H2/O2/N2 flames seeded with BC13 were examined using laser light scattering and a mass spectrometer equipped with a modulated molecular beam sampling system. The results demonstrate that the processes by which the primary combustion product HBO2 is converted to condensed phase jet constituents such as B2O3(liquid) are not interpretable via models based on conventional homogeneous nucleation theories.
