However, their standalone photocatalytic performance remains limited due to rapid charge carrier recombination, particle agglomeration, and low surface activity. In this study, Fe₃O₄ was coupled with graphitic carbon nitride (g-C₃N₄) to form a Fe₃O₄/g-C₃N₄ ceramics nanocomposite, synthesized through a high-energy ball-milling process. XRD, FTIR, XPS, BET, Raman measurements were performed to demonstrate that Fe₃O₄ and g-C₃N₄ were successfully integrated to make a stable heterojunction. The incorporation of Fe₃O₄ reduced the bandgap energy of g-C₃N₄ from 2.81 eV to 2.12 eV, enhancing visible-light absorption. BET analysis revealed a surface area of 49.79 m²/g and mesoporous structure, supporting improved adsorption and charge transfer. Raman shift of T_12g and E_g modes also confirmed that there was a high interfacial interaction between Fe₃O₄ and g-C₃N₄. Under visible-light irradiation, the Fe₃O/g-C3N ceramics nanocomposite achieved 95% degradation of malachite green (MG) within 60 min. The addition of H2O2 further promoted degradation through a photo-Fenton-like mechanism. Scavenger experiments also confirmed that ^•OH and <i>h</i>^<i>+</i> were the main reactive species, which validated the synergistic photocatalytic/photo-Fenton pathway. Furthermore, kinetic analysis followed pseudo-first-order behavior consistent with the Langmuir–Hinshelwood model. The material also demonstrated excellent stability, magnetic separability, and reusability across multiple cycles. The novelty of this work lies in the development of a magnetically recoverable Fe₃O₄/g-C₃N₄ ceramic nanocomposite via a green, solvent-free ball-milling approach, integrating visible-light photocatalysis with Fenton-like activity for sustainable wastewater treatment.</p>\u0000 </div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"62 4","pages":"1737 - 1753"},"PeriodicalIF":2.6,"publicationDate":"2026-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148965536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six different mixes were prepared using RHA-derived activators and without activators. The activation moduli (Ms) ranged from 0.0 to 1.10. The mixes were evaluated for compressive strength, density, water absorption, porosity, capillary water absorption, and microstructural characteristics using scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDX), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). To compare the mechanical strength, total porosity, and water absorption of mixes, a one-way analysis of variance (ANOVA) was conducted at a significance level of 5%. The RHA30 mix (Ms = 1.0) obtained the highest compressive strength of 31.56 MPa at 28 days, compared to just 7.19 MPa for the NaOH-only mix (Ms = 0.0). Bulk density increased from 2265 kg/m³ (MFA-RHA0) to a peak of 2861 kg/m³ (MFA-RHA30) while total porosity and water absorption decreased to 16.83% and 4.51%, respectively. Capillary water absorption was also reduced with the sorptivity coefficient (k) dropping by 15.46% in the optimal RHA mix. Microstructural analyses confirmed the formation of dense N/C-A-S-H and C-A-S-H gels.

Viscosity measurements showed that higher sludge levels significantly increased viscosity from 460 to 920 mPa·s. Thermal analyses revealed that sintering and softening temperatures rose from 734 °C to 798 °C (STD) to 798 °C and 832 °C (S4), demonstrating improved refractory behavior. Microhardness values peaked at ~ 720 Hv in the S1 composition (25 wt% sludge), exceeding both the reference glaze (~ 650 Hv) and higher sludge samples, which showed reduced hardness due to porosity. Gloss decreased progressively from 92 (STD) to 75 (S4), while color parameters remained stable. Leaching tests confirmed that all heavy metals stayed within regulatory limits, although chromium release increased to 0.03 mg/L in S4 but remained below the 0.05 mg/L threshold. Therefore, S1 composition offered the most balanced performance, combining improved hardness, acceptable gloss, and environmental compliance.

The dual-reinforcement strategy leverages the low density and thermal insulating nature of FA, alongside the exceptional hardness of B4C, to achieve superior mechanical and tribological properties while promoting sustainability through the utilization of industrial waste. Comprehensive characterization—including optical, SEM, EDS, and XRD—revealed uniform reinforcement dispersion, strong interfacial bonding, and the formation of strengthening phases such as Al₂O₃, Al₂CuMg, B₄C, and MgZn₂ within the Al matrix. The incorporation of reinforcements led to a progressive reduction in density, accompanied by an increase in porosity at higher loadings, due to clustering and reduced wettability. Notably, the composite with 2 wt.% FA and 6 wt.% B₄C demonstrated the highest hardness and wear resistance, with significant improvements over monolithic AA7075. Wear behavior was systematically studied under varying sliding distances (up to 5000 m) and applied pressures (0.25–1.00 MPa). The wear rate decreased with distance due to the formation of a stable, mechanically mixed layer, while hybrid composites exhibited a delayed transition to severe wear, higher seizure resistance, and reduced thermal softening effects.</p>\u0000 </div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"62 4","pages":"1695 - 1721"},"PeriodicalIF":2.6,"publicationDate":"2026-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148965434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this, a selected composition was subjected to thermal analysis by DTA/TG, and the decomposition behavior of CaCO₃ and H₃BO₃ was determined. Additionally, the solid-state reaction temperature was defined as 900 °C. Six compositions were designed based on the CaO-B₂O₃ binary phase diagram, using calcium carbonate and boric acid as starting materials. The synthesis of calcium borate was carried out at 900 °C for 3 h.
