Abstract

The near-surface infrared spectral changes that occurred on a commercial soda-lime-silicate glass, which was heat treated in SO2/H2O/air atmospheres, were measured, in the region 1200 to 600 cm−1, using attenuated total reflectance Fourier-transform infrared (ATR-FTIR) spectroscopy. Sets of spectra were taken at different angles of incidence of the infrared beam corresponding to successive penetration depths on the surface, hence, giving a surface spectral profile. It was found that the Si-O-Si vibrational band, observed in the region ∼1100 cm−1, is the most affected; with increasing depth the band becomes weaker, depending on the treatment temperature and water content in the treatment atmosphere. The two different sides (the side in contact with the tin bath (tin side) and the opposite side (air side)) were determined to have a different character as a result of the dealkalization treatments.
