Effect of gamma irradiation on the FTIR of cement kiln dust–bismuth borate glasses

Gamma Ray Shielding Parameter of Barium-Boro-Tellurite Glass

“…The FTIR spectra of [(TeO 2 ) 0.7 (B 2 O 3 ) 0.3 ] 1-x (BaO) x glass with x = 0 (0BaO) revealed two broad absorption peak centers at 1300 cm -1 and 1200 cm -1 , and two peaks with small intensity at ~589 cm -1 and ~450 cm -1 . The aforementioned peaks are almost similar with previous work for borate -and tellurite-based glass systems as reported by Sadeek et al, (2015) [16] and Sidek et al, (2009) [15], respectively. The broad peak center at 1300 cm -1 is attributed to the asymmetric stretching vibrations of B-O in the BO 3 unit with non-bridging oxygen from orthoborate, metaborate and pyroborate groups [21].…”

“…From Figure 4, the FTIR spectra of boro-tellurite (0BaO) glass exhibited two broad absorption peak centers at 1200 cm -1 and 1300 cm -1 , and two small intensity peaks at ~450 cm -1 and ~589 cm -1 . These peaks are almost similar to previous research for tellurite- [15] and borate-based [16] glass systems. The broad peak center at 1200 cm -1 was attributed to asymmetric stretching of B-O bonds from BO 4 tetrahedral and orthoborate groups, while another broad peak center at 1300 cm -1 are corresponding to the asymmetric stretching vibrations of B-O in the BO 3 unit with non-bridging oxygen from orthoborate, metaborate and pyroborate groups [17][18].…”

Eco-friendly repurposing of by-pass waste for optics and radiation protection: addressing hazardous material challenges

“…29,30 Furthermore, incorporating By-pass waste into glass composites aligns with global efforts towards sustainable development by reducing landfill use and promoting the recycling of industrial by-products. 31 Additionally, previous studies have indicated that certain waste materials can enhance glasses' optical and radiation-shielding properties. Therefore, By-pass waste was selected to investigate its efficacy in improving these properties while addressing environmental conservation and waste management challenges.…”

Ultrasonic and structural features of some borosilicate glasses modified with heavy metals

“…According to extensive studies using several techniques, such as Fourier transform infrared spectroscopy (FTIR) [9], ultraviolet-visible spectroscopy [10], X-ray diffraction [11], B 11 and Pb 207 nuclear magnetic resonance spectroscopy [11][12][13] and Raman spectroscopy [14,15], the structural and physical properties of these glasses revealed a wide composition range of 20-80 mol% PbO [16]. According to its concentration, PbO can enter the network of sodium borate glass as a network modifier or as a network former [17,18].…”

“…Band de-convolution of infrared spectrum for Na 1.4 B 2.8 Si 0.3 O 5.5 glass.attributed to the asymmetrical stretching vibrations of Si-O-Si of [SiO 4 ] structural unit, and the bands at ∼819-835 cm −1 can be attributed to the stretching vibrations of tetrahedral BO 4 units[36].The weak bands at ∼415-427 cm −1 and at ∼542-561 cm −1 are attributed to vibrations of [PbO 6 ] structural units and to asymmetric vibration of B-O-Si units, respectively. The bands at ∼609-664 cm −1 and at ∼690-717 cm −1 are attributed to bending vibrations of Si-O-Si linkages and to bond bending vibrations of B-O-B linkages of the boron-oxygen network, respectively[9,21,36].…”
