Two key advantages were identified: improved carbon dispersion and in situ generation of SiC whiskers. This work advances the development of no-cement castables by using silica sol as a binder, avoiding the drawbacks of traditional cement systems and enhancing high-temperature performance. The effects of tar additions on the microstructure, phase composition, high-temperature properties, oxidation behavior, and slag erosion resistance of C–S–ASC castables were systematically investigated. Results showed that 4 wt.% tar addition led to more uniform carbon distribution than conventional castables. Industrial Computed tomography (CT) analysis revealed a notable increase in matrix density, indicating effective SiC whisker formation. Consequently, thermal modulus of rupture, oxidation resistance, and slag erosion resistance were significantly improved. Specifically, thermal shock resistance (residual strength ratio = 61.1%) increased by 24% and oxidation resistance (ω = 69.5%) by 20.9%, compared to castables with traditional carbon sources.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196878","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}

In this work, the anti-erosion coatings were prepared by the slurry method using alumina as the filler of coating and aluminum–zirconium coupling agent (DH-550) as additive. The steric effects mechanism of DH-550 was investigated through Fourier transform infrared spectrometer (FTIR), high-temperature abrasion resistance tests, and microstructure analysis after erosion. The results show that the substrate without coatings exhibits poor erosion and abrasion resistance. Upon the addition of DH-550, the hydrolysis of Al2O3 generates an increased density of surface hydroxyl groups, which facilitate the chemisorption of DH-550 onto the Al2O3 surface, forming a protective organic–inorganic hybrid layer. The grafted DH-550 molecules introduce steric hindrance effects, thereby effectively increasing interparticle distances and mitigating agglomeration. Consequently, Al2O3 is uniformly distributed on the substrate surface after drying, enabling the formation of 3Al2O3·2SiO2 and Al2TiO5 phases at the interface during the high-temperature heat treatment. The pores are filled by Al2TiO5 formation, and a dense protective layer is subsequently formed, leading to significantly improved erosion resistance. The overall performance of the sample is optimal when the DH-550 addition amount is 2 wt%.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196875","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}

The effect of dwell time on luminescence properties of reactive sintered samples was also studied. Ultraviolet‒visible spectroscopy revealed a narrower bandgap and an enhanced photoluminescence (PL) intensity in the sample sintered for 6 h, as a result of a higher concentration of oxygen vacancies. PL under 302 nm excitation displayed multi-wavelength emissions peaking at 432, 572, and 653 nm, producing near-cold white light.

Ultra-high temperature ceramic materials (UHTCs), based on carbides, borides, carbonitrides, and nitrides of transition metals—many with melting points exceeding 3000°C—possess the necessary properties for such applications. However, traditional powder metallurgy methods for producing these materials are complex, energy-intensive, and typically require ultra-high temperature equipment. The combustion synthesis (CS) method, also known as self-propagating high-temperature synthesis (SHS), offers a rapid and efficient alternative. It leverages the exothermic heat generated during chemical reactions to produce UHTCs without external heating sources. This review discusses the achievements of CS in synthesizing a wide range of UHTCs—from simple compounds to complex, multicomponent “high-entropy” ceramics—including materials with record-breaking melting points based on carbonitrides, binary carbides, and diborides. There are two primary approaches to producing dense UHTCs: (1) CS of ultra-refractory powders followed by compaction using hot pressing or spark plasma sintering, and (2) simultaneous synthesis and compaction via reactive spark plasma sintering. Overall, the CS method opens exciting prospects for developing advanced materials that meet the demanding requirements of modern industry.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ceramics.onlinelibrary.wiley.com/doi/epdf/10.1111/ijac.70044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These deposits degrade the protective ceramic thermal barrier coatings (TBCs) and environmental barrier coatings (EBCs) in the hot-section. Other particulates present in the environment, such as seasalt and sulfates, are also ingested by GTEs. Although CMAS-induced degradation of TBCs and EBCs have been studied, the effects of these other corrodents on the CMAS deposits, and how CMAS + corrodent mixtures degrade TBCs and EBCs remain unclear. This work examines systematically the effect of the addition of corrodents (CaSO4, seasalt, or Na2SO4) to the CMAS on its melting and crystallization behavior. Various amounts of the corrodents were mixed separately with CMAS glass, and heat treated at various temperatures in air. Mass loss and changes to the chemical compositions were also evaluated. Phase evolution was studied experimentally, and it was compared to prospective equilibrium phases computed using the calculation of phase diagrams (CALPHAD) method. It is found that CaSO4 alters the CMAS most significantly, and it may pose the greatest threat for exacerbating deposit-induced degradation of TBCs and EBCs in GTEs.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196545","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}

Thermally sprayed NiCrAlY bond coats serve as a critical interface between the substrate and the top ceramic coat. In the present study, a comparative analysis was carried out to evaluate the fracture and failure characteristics of atmospheric plasma spray (APS) and high-velocity oxy-fuel (HVOF)-sprayed NiCrAlY coatings under acoustic emission (AE) monitoring of three-point bend test. Thermal sprayed coatings microstructural analysis showed that the porosity of HVOF-sprayed NiCrAlY coatings was 1.56 vol.%, nearly 70.8% less than the 5.35 vol.% of APS coatings, suggesting a much denser coating microstructure. A Young's modulus of 190 GPa was found for HVOF coatings in three-point bend testing, which is 10.5% greater than the 172 GPa found for APS coatings. AE monitoring results revealed that during bend test, APS coatings had a maximum of about 250 AE hits, while HVOF coatings only had about 180 hits. The decrease of 28% AE hit suggests that HVOF coatings have improved ductile fracture behavior and delayed crack propagation. Fracture surface analysis of coatings revealed ductile failure morphology in HVOF coatings and brittle cleavage patterns in APS coatings. The current research findings demonstrate the influence of thermal spray technique on structural integrity of the NiCrAlY bond coat and confirm the effectiveness of AE as a diagnostic tool.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196396","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}
