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.

“…ions rearrange the bonding of the SLS glass and causing the splitting of Si-O-Si bond, hence the bridging oxygen's is converted to non-bridging oxygen's. The formation of NBO's decrease the connectivity of the glasses and the glass structures become weakened [26]. DSC thermogram was recorded for the precursor glass powder to determine the T g and T c temperatures.…”

This paper presents a comprehensive study on thermal, structural and optical properties of novel willemite glass-ceramics. The precursor glass in the ZnO-SLS glass system was successfully prepared using conventional meltquenching technique and willemite (Zn 2 SiO 4 ) glass-ceramics were derived from this precursor glass by a control crystallization process. The effect of heat-treatment temperature on the phase transformation, morphology and size of Zn 2 SiO 4 crystal phase was examined using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM) techniques. Furthermore, fourier transform infrared reflection (FTIR) spectroscopy was used to evaluate the Zn 2 SiO 4 crystal structural evolution. The average size of Zn 2 SiO 4 crystallite obtained from calculation of XRD is found to be in the range 30-60 nm, whereas the grain size observed in FESEM is in range of 200-400 nm. The appearance of SiO 2 , ZnO 4 and Zn-O-Si bands detected from FTIR indicate the formation of Zn 2 SiO 4 crystal phase. Besides, the study of the optical band gap has found that optical band gap of the glass-ceramics decreased as the heat treatment temperature increased. The photoluminescence spectra of willemite glass-ceramics exhibit two different emissions around 525 nm (green) and 585 nm (yellow); exhibit a characteristic of broad absorption band around 260 nm. These two different spectra reveal that the luminescence performance of the willemite glass-ceramics was enhanced with the progression of heat treatment temperature due to different located energy levels of the b-Zn 2 SiO 4 and a-Zn 2 SiO 4 crystalline phase. Such luminescent glass-ceramics was expected to find potential applications in phosphors and opto-electronic devices.

Combined optical and FTIR were measured for binary bismuth borate glass together with samples containing 2.5 -15 mol % Bi 2 O 3 glasses to justify the role of bismuth (Bi 3+ ) ions on the spectral properties. The density and molar volume values were calculated to obtain some insight on the compactness and structural arrangement in the network. DTA measurements were carried out to calculate the thermal transition parameters of the studied glasses and to justify their stability. Optical spectra reveal three strong UV-near visible absorption bands at 250, 275 and 310 nm due to collective absorption of trace iron (Fe 3+ ) ions impurities together with absorption from Bi 3+ ions at 360 nm. The absorption edges reveal an obvious increase with the Bi 2 O 3 content. FTIR spectra reveal vibrational bands characteristic for triangular borate groups at 1200-1600 cm −1 , tetrahedral borate groups at 800 -1200 cm −1 together with interference of Bi-O vibrations upon the introduction of Bi 2 O 3 . The observed bands at about 429, 465, and 595 cm −1 are related to BiO 6 and the band at 879 cm −1 is related to BiO 3 in the host sample 15 % Bi 2 O 3 . Thermal properties are found to depend on the Bi 2 O 3 content depending on the specific role of the formed groups (BiO 6 , BO 3 ) and their function as modifier or former together with the formation of nonbridging oxygens.
