In our study, we focused on the understanding of the compositional dependency of the surface crystallization of quartz solid solutions (Qz-ss) with potentially low CTE. Specifically, we investigated the crystallization of melt-prepared soda–lime–silicate glasses with variable Al₂O₃ content that were doped with lithium in exchange for sodium. Further, the role of ZnO and MgO in the crystallization was evaluated. Despite rather complex glass compositions, the observed cell parameters of the obtained Qz-ss are close to the corresponding ternary Li₂O─Al₂O₃─SiO₂ (LAS) system. Further, a simple model was applied to predict the in-plane stresses in the surface. For modeled compositions down to 5.5 mol% Al₂O₃, formation of a compressive layer for the complete range of the crystalline content can be observed. Our findings illustrate the potential of strengthening glasses through surface crystallization as an alternative to thermal- and chemical strengthening to make glass-packaging more weight competitive. The results can help to optimize glass compositions that can be strengthened by this method.</p>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"17 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ceramics.onlinelibrary.wiley.com/doi/epdf/10.1111/ijag.70023","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146162745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A Three Autocollimation Method for Measuring the Refractive Index of Optical Glass","authors":"Alexander Yurin","doi":"10.1111/ijag.70022","DOIUrl":"10.1111/ijag.70022","url":null,"abstract":"<div>\u0000 \u0000 <p>This article presents a three autocollimation method (TAM) for measuring the refractive index (RI) of optical glass. The popular minimum deviation method (MDM) for RI measurement is accurate, but it is very laborious, since the procedure of determining the minimum possible angle requires many iterations. TAM allows the calculation of RI based on the measurement of the angles of incidence of the beam corresponding to the autocollimation from the mirror located behind the investigated prism, parallel to the entrance face. Measurements must be carried out for all three faces, but it is not necessary to measure the prism angles, since the RI is calculated by solving a system of equations relating the values of unknown parameters. A comparative analysis showed that the accuracy of the proposed method is about 20% higher than the accuracy of classical MDM under the same conditions. A limitation of TAM is the phenomenon of total internal reflection, which limits the measurement range. To implement TAM, a goniometric system with a photoelectric encoder and a set of three reference prisms made of optical glass is used. The experimental absolute error does not exceed ±1·10⁻⁵, which proves the prospect of using the method for high-precision RI measurements. TAM can also be used to study the dispersion characteristics of triangular prisms made of optically transparent materials. TAM increases the accuracy and simplifies the RI measurement process compared to MDM.</p>\u0000 </div>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"17 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146057741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vienna","doi":"10.1111/ijag.70020","DOIUrl":"10.1111/ijag.70020","url":null,"abstract":"<p>Designing a single glass composition for a multidimensional property space is challenging, and the difficulty increases with the number of design criteria. Traditionally, the task is accomplished using multiple statistical models that describe the relationships between composition (C) and property (P) values, i.e., C-P models. Recently, the structure (S)-property (P) statistical modeling has emerged as a complementary approach. The S-P modeling approach has also been shown to be a preferred method for modeling glass properties, particularly when a small data set is available, such as in single-component studies, or when strong nonlinearities exist between composition and properties. The combined model package, C-S-P, implements the concept of generic glass design, i.e., designing glass for performance by first selecting a specific or optimized set of glass network structural groups using S-P models and then transferring the designed structures (genes) to a particular composition using C-S models. This article reviews a set of supporting cases from the previous C-S-P modeling studies of phosphate, silicate, and borosilicate glasses, which are relevant for many critical commercial applications. The methodology for developing the statistical C-S-P database is presented, enabling the application of P→S→C to achieve a generic glass design and optimization, targeting multiple design criteria for both performance and processing properties simultaneously.</p>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"17 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145986773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
