Hydrolysis kinetics of soda lime silicate glass (SLS) with 75 mol% SiO2 in different pH solutions was investigated. Fourier Transform Infrared (FTIR) spectroscopy was used to monitor and confirm the proposed corrosion mechanisms on the surfaces of prepared undoped (SLS) glass together with samples doped with one of the first 3d-transition metal oxides (TMO) (TiO2→CuO) when exposed to an aqueous solution for a short time period. The traditional proposed mechanism of silicate glass corrosion through ion exchange is analyzed in correlation with infrared reflectance vibrational spectra to confirm the suggested mechanism. The effects of transition metal oxides are followed and interpreted.
