Abstract

In order to reveal the combustion characteristics of amorphous boron powder in different atmosphere, experimental studies were carried out using a laser ignition system. Visible wavelength emission spectra and burning flame were recorded using a spectrometer coupled with a high speed camera. The results show amorphous boron can maintain self burning in pure N₂ with light yellow flame, while the combustion in pure O₂ is much stronger with a green flame. Spectroscopic data taken in pure O₂ show obvious BO₂ emission and little BO emission, while those taken in pure N₂ show no BN emission. The highest intensity peak of the emission spectrum of the gas-phase reactant BO₂ is at wavelength of 547.1 nm. No BO₂ emission is detected in O₂/H₂O environment compared to O₂. As the mole fraction of O₂ decreases, the BO₂ peaks at the wavelengths of 471, 492.9, 518.1, 547.1, 579.1 nm are always strong, whereas those of 452 and 620.2 nm gradually fade away in O₂/N₂ environment.
