Studies on Constitution of Vitreous Silicate by Infrared Absorption Spectra

Tsutomu Yanagase* and Yukio Suginohara*

The infrared absorption studies have been carried out on the silicate glasses as an approach to clarify the constitution of molten silicate. As seen in the figures of infrared absorption spectra obtained for the binary silicates of PbO-SiO2, CaO-SiO2, BaO-SiO2, ZnO-SiO2 and Na2O-SiO2 systems, each vitreous silicate gives characteristic spectral curves. From the result of investigation on the absorption band of ν3 vibration due to Si-O stretching mode, it may be predicted that the different kinds of silicate anion can co-exist in vitreous or molten silicates over a certain SiO2 content.
