“…This is an important parameter of the potential to manufacturing devices, namely of optical fibers, where the glass will undergo a reheating process. Being subjected to heating cycles, undesirable crystallization may occur and even in small quantities the crystallization may cause significant light scattering, i.e., attenuating the optical signal and compromising the gain [23,24] achieved in amplifiers.…”

“…In addition, only a weak peak appeared when the BaO concentration was 9 mol%. The bands at 950 and 1200–1500 cm −1 were attributed to the B–O − symmetric stretching vibration of orthoborate groups and the B–O − vibrations of orthoborate anions or pyroborate groups, 20–22 respectively. As shown in Figure 1A, the peak shifts around 950 cm −1 were increased, and the band at 1200–1500 cm −1 center moved toward more energetic vibrations, which can be explained that B–O − vibration enhancement can compensate for the decrease of the characteristic bands at 793 [BO 4 ] and 855 cm −1 [SiO 4 ] 19,20 .…”

“…FT‐IR bands located at approximately 547, 1216, and 1376 cm −1 were caused by the Zn–O stretching vibrations in [ZnO 4 ], 23 B–O stretching vibrations of (BO 3 ) 3− units, and B–O stretching vibrations of trigonal [BO 3 ], 23,24 respectively. Bands at 684–694 cm −1 were attributed to B–O–B bending vibrations of trigonal [BO 3 ] 22,25 . With the increasing content of BaO, the related peak moved to a high wavenumber, indicating that more [BO 3 ] units were presented in the glass network.…”

The extensive application of multilayer ceramic capacitors provides an attractive development for terminal electrode pastes. However, the growing requirement for advanced glass materials used in terminal electrode pastes is substantiated. Therefore, to advance the development of electrode pastes, better development and deeper exploration of glass powder are required. Here, a series of BaO-ZnO-B 2 O 3 -SiO 2 (BZBS) glasses were prepared by melt-quenching technique, which are used to investigate the effect of the introduction of BaO on structure and properties of the ZnO-B 2 O 3 -SiO 2 (ZBS) glass. With the introduction of BaO, the relative amount of [BO 4 ] was much less, which made the glass network structure loosen, decreased the glass transition temperature (T g ) and increased the coefficient of thermal expansion of the glass. The decreasing contact angle was observed on the surface of a barium titanate (BaTiO 3 ) substrate. When the BaO content was around 3-7 mol%, the stability of ZBS glass frit could be strengthened by inhibiting the precipitation of Zn 2 SiO 4 crystal. In addition, to further characterize the effect of glass on terminal electrode paste, BZBS glass powder was adopted to prepare copper electrode paste, which was printed on the BaTiO 3 substrate and subsequently fired at 800 • C for 10 min. With the related copper paste containing ZBS glass doped with 7 mol% BaO, the optimum value of acid resistance and sheet resistance (1.99 mΩ) were exhibited, at which the coated copper paste formed a dense conducting layer.

“…The aforementioned properties of the TeO 2 -based glasses made researchers interested in studying the shielding properties and trying to develop new types of glass based on tellurite oxide as effective materials in radiation 2 of 14 protection [20][21][22].

This research work aims to investigate the radiation shielding ability of a Yb3+-doped calcium borotellurite glass system. The system has the basic composition of CaF2–CaO–B2O3–TeO2–Yb2O3 but is denoted as TeBYbn for simplicity. The effect of increasing the TeO2 content in the glasses from 10 to 54 mol% was investigated, with five different chosen compositions and densities. The Phy-X/PSD program was used to investigate the mass attenuation coefficient (µ/ρ) of the samples. The mass attenuation coefficients were theoretically determined by using an online software for the calculation of shielding parameters. Other parameters were then calculated and analyzed, such as the linear attenuation coefficient (µ), transmission factor (TF), radiation protection efficiency (RPE), effective atomic number (Zeff), and mean free path (MFP). TeBYb5, the glass with the greatest TeO2 content, was shown to have the greatest µ/ρ; however, at greater energies, the differences between the values are practically negligible. µ was shown to increase with density, such as from 0.386 cm−1 to 0.687 cm−1 for TeBYb1 and TeBYb5 at 0.284 MeV, respectively. The least TF was found for samples with a thickness of 1.5 cm, proving an inverse correlation between the thickness of the sample and the TF. The HVL and TVL of the glasses decreased as the density of the samples increased, which means that TeBYb1 is the least effective out of the investigated glasses. The five samples proved to have a lower MFP than some other shielding glasses, demonstrating their capabilities as radiation shields. Based on the calculated parameters, TeBYb5 indicated the greatest photon attenuation ability.
