Study of corrosion processes in glass by a multitechnique approach. Part 2. Infrared spectroscopy

Infrared reflection absorption spectroscopy (IRRAS) was used to study surface changes associated with corrosion of glass in aqueous and acidic solutions. Variations in the intensities and positions of the bridging (Si-O-Si) and nonbridging (Si-O-M) stretching vibrations are discussed as functions of the leaching conditions. Existence of molecular water in glass was discussed in terms of the measured infrared reflectance and transmittance spectra. Quantitative analysis of glass surfaces by infrared is possible if the values of reflection coefficients and extinction coefficients of the different absorption bands could be determined.
