“…This process spanned a temperature range extending from ambient conditions up to 1000°C. The analysis focused on identifying key characteristic temperatures that are crucial for understanding the thermal behavior and stability of the glass materials [13,18]. These temperatures included the glass transition temperature (T g ), which marked the onset of softening in the glass and was identified at the point where the first endothermic deviation occurs on the DTA curve [17][18][19][20].…”

“…Additionally, the onset of crystallization temperature (T x ) was determined at the beginning of the exothermic deviation, indicating the start of crystalline phase formation. The peak temperature (T c ) of crystallization was identified as the apex of the exothermic peak, highlighting the point of most intense crystallization activity [13,18]. Subsequent studies aimed at detecting the presence of crystalline phases after the thermal treatment, which involved keeping the glass powder at the T c in an air atmosphere for five hours [15,16].…”

“…Bismuth zinc borosilicate glasses are environmentally friendly due to their use of bismuth oxide instead of lead oxide [13], which has historically been a common component in many glass formulas despite its significant health and environmental drawbacks. The shift towards bismuth oxide reflects growing ecological concerns and stricter regulations, making these glasses a safer and more eco-friendly choice for various applications.…”

The influence of composition on the structure, thermal, and some physical characteristics of bismuth borate glasses, formulated as 55Bi2O3–(35-x-y)B2O3–(5+x)ZnO–(5+y)SiO2 (where 0 ≤ x, y ≤ 15 mol%), was investigated. Comprehensive analyses were conducted using techniques such as X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier-Transform Infrared Spectroscopy (FTIR), Differential Thermal Analysis (DTA), and Dilatometry. XRD confirmed the amorphous nature of the glass samples, while FTIR spectroscopy revealed that the glasses are primarily composed of BO4, BO3, BiO6, BiO3, ZnO4, and SiO4 structural units. DTA provided further evidence of the samples' glassy state and insights into key temperatures like glass transition (Tg), crystallization (Tc), and melting (Tm). The study finds that substituting B2O3 with SiO2 increases all characteristic temperatures, whereas replacing it with ZnO decreases Tg and Tc but increases Tm. The maximum thermal stability, indicated by a ΔT of 99°C, was observed in the glass with a 55Bi2O3–20B2O3–20ZnO–5SiO2 composition. Dilatometric measurements showed that the investigated glasses have a high coefficient of thermal expansion (10.0–10.7 ppm/°C) values, a low glass transition temperature (345–376°C), and a low dilatometric softening temperature (364–392°C). Additionally, the density and molar volume of the samples were accurately determined.

“…The mixed alkaline effect in glasses is evident in their structural, thermal, and optical characteristics, according to Walia et al [17]. Nonetheless, there aren't many reports on bismuth borate glasses containing MgO-BaO in the literature [18]. However, Cadmium oxide (CdO) possesses a variety of attractive qualities.…”

The expression (70-x)B2O3-10ZnO-10CdO-10MgO-xBi2O3 Glasses containing B2O3, ZnO, CdO, MgO, and variable amounts of Bi2O3 were created using the melt quenching process. The observed rise in both density and molar volume of the glass samples as the Bi2O3 level increases suggests the formation of a more expanded structure with greater Bi2O3 content. There is a good degree of agreement between the observed values of band gap energy and Urbach energy estimated from the ASF model and Tauc model. The decrease in Eopt may be attributed to the increased concentration of non-bridging oxygen (NBO) inside the glass network, resulting in a disordered glass structure. The measured values of Λ and A indicate that the current glasses belong to group-II, namely typical ionic (basic) oxides. The non-linear optical properties of the current glasses, specifically n2, χ (1), and χ (3), showed an increase as the glass composition increased. The current glasses provide several benefits, such as a larger density. These glasses have a greater polarizability and an improved refractive index, making them highly sought-after materials for non-linear optical applications.
