Abstract

Measurement of infrared emission spectra for boron-based pyrotechnic combustion has enabled the elucidation of a number of boron oxidation products. The raw spectra were corrected for instrument responsivity and atmospheric attenuation for the region 1500 to 3000 cm−1. The alkali metal metaborates and boron oxide (B2O3) were among the principal combustion products depending on which of three different oxidants were used. In addition, thermochemical modeling studies were undertaken on each composition to predict the combustion products. The thermochemical modeling data were qualitatively in agreement with the identified combustion products.
