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}

In this study, a series of Li₂O–Al₂O₃–SiO₂ (LAS) transparent glass-ceramics were successfully prepared using 50 wt% spodumene smelting slag as the primary raw material. The effects of co-doping with ZrO₂ and BaO on the structure and properties of the glass-ceramics were systematically investigated. Unlike most previous studies that focused on single-component modification, this work highlights the novel co-doping strategy of BaO and ZrO₂ in a waste-derived LAS system, and systematically investigates their synergistic and antagonistic effects on nucleation, crystallization, and properties. The optimal sample, treated at 600°C for 8 h for nucleation and 750°C for 2 h for crystallization, exhibited high crystallinity, a transmittance of 90.67% at 550 nm, a Vickers hardness of 7.07 GPa, and a relatively low coefficient of thermal expansion (CTE ≈ 8 × 10⁻⁶ K⁻¹). Low ZrO₂ content leads to insufficient nucleation, resulting in grain agglomeration and opacity, whereas excessive ZrO₂ tends to act as a network former rather than a nucleating agent, thereby reducing the overall crystallinity. Partial substitution of SiO₂ with BaO, functioning as a network modifier, induced local depolymerization of the glass network and effectively suppressed excessive grain growth, thereby maintaining high optical transparency. This work provides a promising route for the high-value utilization of spodumene smelting slag and offers useful insights for designing high-performance LAS transparent glass-ceramics.</p>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"17 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145887725","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}

However, designing proper temperature settings for this technique is challenging due to the non-continuous temperature profile between stations and their interdependence. This study employs finite element simulations to analyze the heating and molding behaviors of a positive meniscus aspheric lens under various temperature settings. The results reveal that the glass temperature increases progressively across heating stations but does not reach the target due to limited heat absorption. Temperature gradients induce tensile stress during heating, while compressive stress during pressing decreases exponentially with higher heating temperatures due to stress relaxation. The molding temperature is critical for complete lens filling, with 580°C identified as the minimum requirement for P-SK57 glass. Additionally, increasing the molding temperature to 590°C expands the number of suitable temperature settings, offering greater flexibility in temperature selection. Out of 60 design groups, 24 meet all process criteria. The first heating station temperature should not exceed 400°C to minimize the risk of excessive thermal shock. Additionally, all heating stations must collaboratively generate a uniform, sufficiently high final heating temperature to control maximum compressive stress during pressing. This work establishes a framework and provides systematic guidelines for selecting optimal heating and molding temperature settings in multi-station molding, enhancing heating efficiency, reducing thermal stress, and ensuring high-quality replication. The findings would contribute to advancing multi-station PGM technology and offer practical insights for optimizing industrial-scale optical manufacturing.</p>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"17 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145626380","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}

First, we combine the Johnson‒Mehl‒Avrami‒Kolmogorov equation with laser thermal treatment curves, varying laser parameters (repetition rate and pulse energy). This investigation clarifies crystallization conditions during irradiation and identifies those required to form NG in crystalline regions. Second, we propose an explanation for the unexpected superior thermal stability of cNG compared to pNG, as reported in the literature. Our model predicts a 200°C improvement considering 1% retardance drift over 25 years. Finally, we map the domains of existence and coexistence of pNG and cNG within a typical repetition rate - pulse energy landscape.
