Abstract

The chemical state of fluorine and the effect of fluorine addition on the degree of polymerization of silicate network have been investigated for the CaO-SiO<sub>2</sub>-CaF<sub>2</sub> and CaO-SiO<sub>2</sub>-CaF<sub>2</sub>-FeO<sub>x</sub> glasses using the X-ray photoelectron spectroscopy (XPS) and Mössbauer spectroscopy measurements. The F1s XPS spectra indicate that the fluorine is dominantly coordinated with calcium rather than silicon. The O1s XPS spectra for the CaO-SiO<sub>2</sub>-CaF<sub>2</sub> glasses and the values of Fe<sup>2+</sup>/Fe<sup>3+</sup> obtained by Mössbauer spectra for the CaO-SiO<sub>2</sub>-CaF<sub>2</sub>-FeO<sub>x</sub> glasses indicate that CaF<sub>2</sub> addition does not depolymerize the silicate network for both systems.
