Abstract
Investigation of the ignition of 24 µm boron particles is investigated in a shock tube at a pressure of 8.5 atm. and temperature of 2500 K in atmospheres of pure O2,1% SF6 with 99% O2, and 30% H2O with 70% O2- Data collected using emission spectroscopy and filtered photodiode detectors is presented. Based on experimental and theoretical investigation, a new interpretation of data presented in previous work is put forward. Following this hypothesis, it is found that addition of Fluorine to the ambient oxidizing atmosphere increases the rates of reaction and higher reaction temperatures during oxide layer removal from boron particles compared to tests in pure O2.
