This challenge arises because molybdenum and rare-earth species, frequently present in HLW compositions, possess a pronounced tendency to initiate crystallization processes. Such crystallization not only causes deviations in the final glass properties from the desired design specifications but also threatens the operational reliability of the glass-melting system. Although the crystallization behavior of glass during vitrification is known to be critically dependent on its composition, a systematic investigation into this relationship remains notably absent. Herein, the studies that address this dependence through compositional design and characterization are still quite limited. In the present work, simulated waste glasses with controlled variations in alkaline earth oxide, B₂O₃, MoO₃, and rare-earth oxide concentrations were prepared and analyzed to examine the role of composition in governing crystallization behavior. Our results reveal the competitive crystallization of two primary phases within the simulated glass systems, namely calcium molybdate (CaMoO₄) and oxyapatite (Ca₂Ln₈(SiO₄)₆O₂, where Ln denotes lanthanide elements). This competition is composition-dependent; in particular, higher levels of B₂O₃ and MoO₃ markedly enhance the precipitation of CaMoO₄ while inhibiting oxyapatite. Conversely, enriching the glass with alkaline earth and rare-earth oxides promotes the development of the oxyapatite phase. This observed competitive crystallization mechanism establishes a theoretical framework for tailoring glass crystallization behavior through compositional design of the base glass.</p>\u0000 </div>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"17 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148324076","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}

Earlier models were found to be overly conservative, while newer models had a not insignificant rate of false positives and negatives, with a drop off in predictive accuracy along the nepheline prediction boundary. Only partial or limited explanations for this drop in accuracy have hitherto been put forward, for example, experimental inaccuracies or insufficient data points. This research presents evidence consistent with a primary cause being differences in surface area to volume ratio (SA/V) between small experimental glass samples and large-scale canister glasses. Furthermore, a new simplified, simulated (non-radioactive) HLW glass composition (KE1) has been designed as a starting point for experiments that focus on the low accuracy region of nepheline predictor models, lying between compositions that are prone to precipitate nepheline and compositions that are not. This glass has been characterized using multiple techniques, and several experiments have been designed and implemented to highlight the marked effects of SA/V on the outcome of the product consistency test (PCT-B, ASTM C1285-21) used to validate the chemical durability (as measured by PCT tests) of nuclear waste glasses destined for geological disposal.</p>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"17 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ijag.70034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148324106","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}

The main objective of conditioning is to cool the glass exiting the furnace to a suitable temperature for container forming. Currently, this stage is managed based on the experience of operators, which is functional but not optimized for energy efficiency. While several approaches to minimizing energy consumption based on process control using physical modeling have been proposed in the literature, they do not completely account for all the involved variables. Moreover, none of these studies leverage the power of data to predict energy consumption patterns. In this paper, we introduce a data-driven method to minimize energy consumption during the glass conditioning stage. We applied this methodology to a specific production line and tested it under various scenarios, achieving potential savings of 5% to 45% in energy consumption. Operational validations in two additional real forehearths showed energy reductions of 26.3–89.3 kWh per operating hour, corresponding to relative savings of 8.2%–22.1%, including a same-production A/B test.

These temperatures depend on burners that must balance thermal efficiency with emission reductions. This article reviews the development of combustion systems in glass furnaces, focusing on their impact on energy consumption and pollutant generation. Primary combustion methods are analyzed alongside recent burner designs that target environmental objectives. Air-fuel systems remain common due to their simplicity and low capital cost; however, they provide limited heat recovery. Oxy‑fuel combustion removes nitrogen and improves radiative heat transfer in a CO₂‑rich atmosphere, thereby increasing heat utilization. Regenerative air‑fuel furnaces remain dominant for float and container glass because of robustness and effective heat recovery, yet the high nitrogen content of combustion air and preheat temperatures generate NO_x. Hybrid concepts that combine limited oxy‑fuel combustion with electric boosting offer a route to lowering CO₂ and NO_x emissions while improving efficiency. Advanced burner designs, including staged, flame‑shaping, multi‑fuel, and flameless, are surveyed for their ability to reduce peak flame temperatures, improve thermal uniformity, and achieve notable NO_x reductions. The analysis indicates that the integration of enhanced burner design with hybrid and oxy-fuel methods offers one of the most feasible pathways for achieving lower emissions, higher efficiency, and cleaner glass melting.</p>","PeriodicalId":13850,"journal":{"name":"International Journal of Applied Glass Science","volume":"17 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ijag.70044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148282270","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}
