“…Recent investigations have stressed that glass shields [14][15][16][17][18][19][20] are one of the most ambitious materials that might be used as an alternative for conventional materials that are disadvantaged in certain ways. Researchers in the literature [21][22][23][24][25][26][27][28][29][30] are particularly interested in glass structures because of the high permeability they provide and the exceptional mechanical properties they possess. It has also been pushed to a position where it is emphasized and developed in daily radiation safety practice because of the non-toxic nature of glasses and the chemical compositions that may be synthesized at high densities.…”

We present elastic moduli, gamma radiation attenuation characteristics, and transmission factor of barium–tungstate–phosphate (BTP) glasses with the chemical formula (60-y)BaO-yWO3-40P2O5, where y = 10 (S1)–40 (S4) in steps of 10 mole%. Different types of mathematical and simulation approaches, such as the Makishima–Mackenzie model, the Monte Carlo method, and the online Phy-X/PSD software, are utilized in terms of determining these parameters. The total packing density (Vt) is enriched from 0.607 to 0.627, while the total energy dissociation (Gt) is enriched by increasing the WO3 content (from 52.2 (kJ/cm3). In the investigated glasses, increasing tungstate trioxide (WO3) contribution enhanced Young’s, shear, bulk, and longitudinal moduli. Moreover, Poisson’s ratio is improved by increasing the WO3 content in the BTP glasses. The 20BaO-40WO3-40P2O5 sample possessed the highest values of both linear (µ) and mass attenuation (µm) coefficients, i.e., (µ, µm)S4 > (µ, µm)S3 > (µ, µm)S2 > (µ, µm)S1. Moreover, the 20BaO-40WO3-40P2O5 sample had the lowest values of half (HVL) and tenth (TVL) layers, i.e., (half, tenth)S4 < (half, tenth)S3 < (half, tenth)S2 < (half, tenth)S1. The effective atomic number (Zeff) of the studied glasses has the same behavior as µ and µm. Finally, the 20BaO-40WO3-40P2O5 is reported with the minimum values of transmission factor (TF) for all the BTP investigated at a thickness of 3 cm. In conclusion, the sample with composition 20BaO-40WO3-40P2O5 which has the maximum WO3 reinforcement may be a beneficial glass sample, along with its advanced mechanical and gamma ray shielding properties.

“…Among them, the inorganic glass binder plays a vital role in the sealing conductive paste, which not only has tight relationship with the sintering temperature of the paste but also can improve the bonding capability among the metal conductive powder, metal conductive paste, and barium titanate (BaTiO 3 ) substrate. Currently, ZnO–B 2 O 3 –SiO 2 2–6 and BaO–B 2 O 3 –SiO 2 7–9 are extensively used glass systems, with excellent acid resistance, lower sintering temperature, and other outstanding properties in the conductive pastes.…”

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.
