FTIR Spectral Analysis of Corrosion Mechanisms in Soda Lime Silica Glasses Doped with Transition Metal Oxides

Abstract

Hydrolysis kinetics of soda lime silicate glass (SLS) with 75 mol% SiO 2 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) (TiO 2 →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.

The effects of γ-radiation on model vitreous wasteforms intended for the disposal of intermediate and high level radioactive wastes in the United Kingdom

“…These assignments are in good agreement with previous investigations of alkali-borosilicate glasses [35,36,[38][39][40][41][42], and specifically Fe-rich alkali-borosilicates [39]. Additional bands were present in the G78 and MW-25% glass samples at 800 cm À1 and 1275 cm À1 respectively; these were fitted to B-O-B bending and stretching modes in BO 4 units [36][37][38]. The intensity of this band was observed to be strongly correlated to higher boron content and the presence of BO 4 units.…”

Shielding behavior of V2O5 doped lead borate glasses towards gamma irradiation

“…Some scientists have noticed the same observations in other glasses [48,49], and they have related them to the weakening of the already nonperiodic network structure or to changes in the bond angles and/or bond lengths between the building structural units as recently suggested by various authors [50,51].…”

Optimization of High Conducting Na3Zr2Si2PO12 Phase by new Phosphate Salt for Solid Electrolyte

“…Sample N3 exhibits a less intense peak near these bands as compared to other samples. Apart from this, the bands ∼ 920-925 cm −1 and 1032-1064 cm −1 are attributed to the stretching of P-O (NBOs) modes and stretching of Si-O modes in NBOs, respectively [41,42]. However, an intense band ∼ 1096 cm −1 corresponds to the antisymmetric stretching of bridging oxygens in Si-OSi groups within the tetrahedron [43].…”
