“…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.

“…In ternary system glasses, in which the matrix is formed by SiO 2 and B 2 O 3 and one modifying component, the crystallization process generally has a single-stage or multi-stage character. The products of crystallization are usually borates (β-BaB 2 O 4 [ 7 ], Ba 2 Zn(BO 3 ) 2 [ 8 ], Mg 2 B 2 O 5 [ 9 ], CaB 2 O 4 [ 10 ]) and silicates (Ba 5 Si 8 O 21 [ 7 ], BaZnSiO 4 [ 8 ], CaSiO 3 , Ba 4 Si 6 O 16 [ 10 ]) in lower and higher temperature ranges, respectively. In the case of glasses containing P 2 O 5 and B 2 O 3 as matrix formers, the crystallization has a multistage character and the main products, at both lower and higher temperatures, are phosphates, e.g., Zn 2 P 2 O 7 [ 11 ], Li 3 Fe 2 (PO 4 ) 3 , LiFeP 2 O 7 [ 12 ], BaP 2 O 5 , BaBPO 5 , and BPO 4 [ 11 , 13 ].…”

“…The authors of the publication concluded that the formation of the barium borate crystalline phase requires a lower activation energy, as it is generated in a loose borate-rich glass network structure, while the barium silicate crystalline phase has to be formed in a more interlocked silicate glass network structure. A similar approach to the study of glass crystallization was adopted by Kržmanc et al [ 9 ], Liu [ 12 ], and Kalenda [ 13 ], while Zhu et al [ 10 ] also considered the influence of the size of ions building the glass matrix on the type of crystallizing phase. Both Zhu et al [ 10 ] and Hu et al [ 14 ] agreed that the larger a cation’s size, the lower its mobility, and thus the smaller the possibility of its occurrence in the crystallizing phases.…”

Glasses and devitrificates from the SiO2–B2O3–P2O5–K2O–CaO–MgO system with constant contents of SiO2 and P2O5 network formers, modified by the addition of B2O3, were analyzed. All materials were synthesized by the traditional melt-quenching technique. The glass stability (GS) parameters (Krg, ∆T, KW, KH) were determined. The effect of the addition of B2O3 on the GS, liquation phenomenon, crystallization process, and the type of crystallizing phases were examined using SEM-EDS, DSC, XRD, and Raman spectroscopy imaging methods. It was observed that the addition of B2O3 increased the tendency of the glass to crystallize. Both phosphates (e.g., Ca9MgK(PO4)7, Mg3Ca3(PO4)4), and silicates (e.g., K2Mg5(Si12O30), CaMg(Si2O6), MgSiO3) crystallized in the studied system. The Raman spectrum for the orthophosphate Mg3Ca3(PO4)4 stanfieldite type was obtained. Boron ions were introduced into the structures of crystalline compounds at high crystallization temperatures. The type of crystallizing phases was found to be related to the phenomenon of liquation, and the order of their occurrence was dependent on the Gibbs free enthalpy.

In this study, 3MgO-B2O3-xwt%BCB-ywt%H3BO3 (2 ≤ x ≤ 8, 0 ≤ y ≤ 20) ceramics were sintered at the optimum temperature to form Mg3B2O6 and MgO phases. The effects of H3BO3 and BCB on product characteristics, phase transition, microstructure, and microwave properties of 3Mg-B2O3 ceramics were investigated. The intensities of diffraction peaks of two phases varied with changing the x and y values. After sintering at 950 °C, the ceramics with x = 6 and y = 15 achieved excellent microwave properties with a εr of 6.72, Q × f of 83205 GHz, and τf of −65.05 ppm/℃. Besides, the ceramic with x = 8 and y = 5 sintered at 925 ℃ also achieved good microwave dielectric properties with a εr of 6.64, Q × f of 78173 GHz, and τf of −57.27 ppm/℃. The sintering temperatures of above both ceramics are well lower than the melting point of Ag, showing promising applications in low temperature cofired ceramic devices. In particular, these two ceramics can be used as potential candidate materials for microwave ceramics for 5G technology, provided that τf can be further optimized.
