“…The half-width and intensity were unconstrained variables when the curve-fitting was made. Based on previous studies, [26][27][28] the frequency center near 885 cm − 1 corresponded to Q 0 , and that at 950 cm − 1 corresponded to Q 1 . The frequency centers near 1 015 cm − 1 and 1 065 cm − 1 were respectively assigned to Q 2 and Q 3 .…”

“…The average number of bridging oxygen atoms was employed to explain the change of the silicate structural network, which was equal to the number of bridging oxygen atoms of each structural unit multiplied by their area proportion. 7,8,28) Figure 4 presents the average number of bridging oxygen atoms of the CaO-Al 2 O 3 -SiO 2 -Na 2 O-CaF 2 mold fluxes at different cooling rates. The average number of bridging oxygen atoms slightly increased with the increase of the cooling rate, as indicated by the increase of the polymerization degree of the silicate structural network with the increase of the cooling rate of the glasses.…”

“…Within a certain content, increasing the B 2 O 3 content can reduce the strength of the network structure, and decrease the slag viscosity and apparent activation energy. Lai et al [ 133 ] found that B 2 O 3 leads to the formation of [SiO 4 ] 4− structures that increase the polymerization of a CaO-Al 2 O 3 -SiO 2 -TiO 2 -B 2 O 3 system. The B and O atoms mainly form two structures, [BO 3 ] 3− trigonal planar and [BO 4 ] 5− tetrahedron.…”

“…These peaks were scanned to obtain high-resolution core-level spectra of the different elements, as shown in Figure 7B-E. According to previous studies, 33,41,42,46 the XPS binding energies were at approximately 73.5 ± 0.3 eV for [AlO 4 ], 41,47 74.2 ± 0.3 eV for [AlO 6 ], 41,47 191.9 ± 0.3 eV for [BO 3 ], 33,42 192.6 ± 0.3 eV for [BO 4 ], 33,42 457.9 ± 0.3 eV for [TiO 4 ], 46,48 459 ± 0.3 eV for [TiO 6 ], 46,48 530.0 ± 0.3 eV for FO, 49 531.2 ± 0.3 eV for NBO, 33,42 and 532.2 ± 0.3 eV for BO. 33,42 Deconvolution of the O 1s, B 1s, Al 2p, and Ti 2p curves was used to fit Gauss-Lorentz curves based on the above-assigned bands to determine the peak positions of different structural sites.…”

“…Al 2 O 3 , Na 2 O, and TiO 2 were selected as the secondary material due to their functions on glass property adjustment. 24,28,33 Effects of B/Si ratio and B 2 O 3 content on the viscosity and melt structure evolution of B 2 O 3 -SiO 2 -Al 2 O 3 -Na 2 O-TiO 2 (BSANT) glass in the temperature range of 950-1100 • C were investigated by using rotational viscometer, Raman spectroscopy, and x-ray photoelectron spectroscopy (XPS). Since B-, Al-, and Ti-related structure units could have different forms in glass melt, which also play a role on melt properties depending on their amount, a detailed analysis on the evolution of Si-, B-, Al-, and Ti-related units in the melts of the designed glass lubricants was also carried out to reveal the mechanism of the glass property change.…”
