N2 - The infrared emission spectra of CaF2-CaO-SiO2 melt were investigated by a method combining infrared emission spectroscopy and the hot-filament technique. Emission for spectra related to Si-O bond can be observed by this in situ technique. The influence of SiO2 and fluoride content on the spectrum was investigated, and the emission attributable to bonds corresponding to silicon-bridging oxygen and silicon-non bridging oxygen was discussed. Results suggest that fluoride ion dominantly substitutes for a non-bridging bond in low SiO2 concentration region. The structure of silicate was compared with calculated infrared emission of Si-F-O.
