Inclusions-primarily oxides and complex silicates-exhibited spherical, triangular, or quadrilateral morphologies with sizes below 10 µm. Reducing inclusion density markedly enhanced plane castability, surface smoothness, lamination factor, and ductility. To achieve this, we developed a two-step purification approach combining argon bubbling via a dispersion gas-permeable brick with a zirconia-based foam-ceramic filter, lowering inclusion densities to below 200 inclusions mm⁻² and effectively preventing nozzle clogging.

The sulfide capacity was determined using a gas-slag equilibrium method under a CO-CO₂-SO₂-Ar mixed atmosphere, while structural variations were analyzed through Fourier transformation infrared spectroscopy (FTIR), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). These techniques collectively elucidated the mechanisms by which FeO and MgO regulate slag viscosity and sulfide capacity through modifications in depolymerization behavior. The addition of MgO (6 wt.%–10 wt.%) increased the viscosity and critical temperature (T_cr) of slag. The increase in FeO content (5 wt.%–25 wt.%) also reduced slag viscosity. However, due to the phase transformation from spinel to melilite and clinopyroxene, the T_cr initially decreased before subsequently rising. Additionally, the sulfide capacity of slag increases with the addition of FeO and MgO contents. And the increase amplitude of sulfide capacity during FeO increase from 5 wt.% to 15 wt.% exceeds that observed between 15 wt.% and 25 wt.%. Complementary FTIR, Raman, and XPS spectroscopic analyses demonstrated that FeO and MgO increased free oxygen ion content while reducing the average bridging oxygen number from 2.18 to 1.63, indicating reduced polymerization degree of the slag structure. This structural depolymerization consequently enhances slag fluidity and desulfurization performance. Based on those findings, it is recommended to gradually increase the content of basic oxides, which commensurate with the extent of iron oxide reduction to sustain adequate fluidity and sulfide capacity.</div></div>","PeriodicalId":16461,"journal":{"name":"Journal of Non-crystalline Solids","volume":"666 ","pages":"Article 123711"},"PeriodicalIF":3.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678929","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}

This study elucidates the orientation effect of grain boundaries on strengthening mechanisms that has not received due attention by far. Our findings reveal that composites with properly aligned grain boundaries exhibit superior strength compared to those with randomly oriented boundaries. This orientation-dependent strengthening originates from two synergistic mechanisms: controlled initiation of shear bands at properly oriented interfaces, and regulated propagation pathways for local shear during plastic deformation.
