“…Sanbornite and Ba5Si8O21 have received considerable attention in recent years due to their desirable formation as acicular aggregates, leading to a considerable strengthening of the glassceramics produced and due to their high thermal expansion, which has led to their wide investigation for solid-oxide fuel cell sealant materials [5,15]. In particular, sanbornite-based glasses display volume nucleation and thus have long been of interest to researchers looking into the fundamental process of crystallization [16][17][18][19][20][21][22]. When doped with rare-earth elements, these materials can be used as light emitting diode materials [23,24].…”

We report here the analysis of vibrational properties of the sanbornite (low-BaSi2O5) and Ba5Si8O21 using theoretical and experimental approaches, as well as results of high temperature experiments up to 1100-1150˚C. The crystal parameters derived from Rietveld refinement and calculations show excellent agreement, within 4%, while the absolute mean difference between the theoretical and experimental results for the IR and Raman vibrational frequencies was <6 cm-1. The temperature-dependent Raman study renders that both sanbornite and Ba5Si8O21 display specific Ba and Si sites and their Ba-O and Si-O bonds. In the case of the stretching modes assigned to specific Si sites, the frequency dependence on the Si-O bond length exhibited very strong correlations. Both phases showed that for a change of 0.01 Å, the vibrational mode shifted 10 ± 2 cm-1. These results are promising for using Raman spectroscopy to track in situ reactions under a wide variety of conditions, especially during crystallization.

“…15 Fundamental studies of nucleation in some common systems, such as lithium or barium silicates, have demonstrated an improved understanding of nucleation mechanisms using newly available or recently improved analytical methodologies. 41 Our ability to find and characterize the morphology of early-stage nucleation as shown in the electron microscopy image from nucleation of barium disilicate, Figure 10, emphasizes the scale and complexity inherent to these types of problems. As glass-ceramic systems become even more important in new technical applications, the solution to new material inventions will depend on even greater advances in characterization.…”

Glass is a material with a rich history and a bright future. Due to its outstanding properties and its versatility, it is a key material in many applications. In this paper, we present a variety of these applications in which glass is playing, and will continue to play, a significant role, including communication technologies, the semiconductor industry, advanced displays, mobile consumer electronics, healthcare, and automotive. Other critical considerations enabling continuous progress in glass science and engineering, such as improved modeling tools and characterization techniques, increased sustainability of the glass-making process, and talent development, are also discussed.

“…The glass studied in this work is the barium disilicate (BaO.2SiO2). This material has an interesting feature: internal nucleation and crystallization can occur from tempered glass without addition of nucleating agents (CAI et al, 2020), becoming glass-ceramics with a wide range of applications, such as LEDs, sealing of solid fuel cells, and so on (EVARISTO et al, 2020).…”
