Initially, we evaluated nine commonly used monomers and selected acryloyl morpholine, propoxylated neopentyl glycol diacrylate, and trimethylolpropane ethoxylated triacrylate based on their quantitative performance. We then employed a formulation experimental design to determine the optimal monomer ratio of 25:60.9:14.1. Furthermore, we optimized the prepolymer (epoxy acrylate) and plasticizer (2,2,4-trimethyl-1,3-pentanediol diisobutyrate) contents to minimize monomer shrinkage, selecting optimal values of 20 wt.% and 10 wt.%, respectively. Based on these optimizations, we determined the ideal concentrations of photoinitiator, dispersant, and thixotropic agent to be 3, 2, and 2 wt.%, respectively. Finally, using the optimized resin formulation, we prepared a high-solid-content Si3N4 slurry and successfully printed high-precision, complex Si3N4 green structures. This demonstrates the practical applicability of the optimized vat photopolymerization resin formulation, laying a solid foundation for the development of Si3N4 ceramics in DLP 3D printing.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814631","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}

While porous ZrB2 enables coolant flow, dense ZrB2 offers structural integrity. However, achieving a reliable ceramic-to-metal connection remains a significant challenge due to the inherent differences in their physical, chemical, and mechanical properties. This study investigates the brazing process of both porous and dense ZrB₂ UHTCs to zirconium metal (Zr). Zr was selected due to its thermal expansion properties closely matching those of ZrB₂, reducing thermal stress at the interface and enabling coolant transfer into porous ZrB₂ from the supply reservoir. The brazing temperature of 1650°C was selected based on the Zr–ZrB₂ phase diagram to ensure eutectic melting without compromising the structural integrity of the base materials, and the filler composition was selected to enhance wetting and spreading. The results demonstrate that dense ZrB₂ forms robust and continuous interfaces with Zr metal, while porous ZrB₂ presents greater challenges due to thermal expansion mismatches and paste infiltration. These findings provide valuable insights into ceramic–metal joining for aerospace high-performance thermal protection systems under extreme conditions, which would reinforce the real-world impact.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ceramics.onlinelibrary.wiley.com/doi/epdf/10.1111/ijac.15161","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814846","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}

In this study, thermal conductivity, thermal expansion coefficient, elastic modulus, and other parameters of alumina‒silica refractories were tested, and the thermal shock resistance of alumina‒silica refractories was evaluated using the values of the dimensionless parameters Π and RΠ calculated based on the Buckingham Π theorem of dimensional analysis. The results demonstrate that the order of magnitude of RΠ values of clay and high-alumina bricks with alumina contents of 45%–65% is consistent with residual strength ratios. Due to higher proportion of glass phase and quartz, the lower work of fracture for clay bricks (38% alumina content) resulted in a relatively high value of the dimensionless parameter RΠ. Nevertheless, the trajectory of RΠ value remains aligned with its resistance to thermal shocks of other samples. The interrelationships among multiple physical parameters and their contributions to thermal shock resistance were revealed by the dimensional analysis, which lays a theoretical foundation for the expedited assessment of thermal shock resistance and the design of high-performance refractories.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814965","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}

B4C was selected based on its ability to oxidize at lower temperatures than SiC, a typical self-healing agent. B4C/SiC powder mixtures were studied for their high-temperature oxidation behavior, revealing reaction initiation around 600°C during constant heating rate. At 1000°C, B4C oxidation accelerated SiC oxidation by 15 times. Several shFRCs with B4C/ SiC interlayer were fabricated to investigate self-healing behavior. Results showed strength recovery after heat treatment at 650°C for 1 h with ≥6 vol% B4C, and at 600°C for 1 h with ≥12 vol% B4C. However, treatments above 700°C led to no strength recovery due to component degradation from oxide formation. The study concludes that optimizing self-healing improvers requires consideration of their stability prior to reaction, heat generation relative to the amount added, and characteristics of the produced oxide. In the case of B4C, 12 vol% with maximized self-healing performance at 600°C is optimal. This research demonstrates the potential of B4C in lowering the effective self-healing temperature of shFRCs, while emphasizing the importance of balancing improver content and treatment temperature to maintain the composite's integrity.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ceramics.onlinelibrary.wiley.com/doi/epdf/10.1111/ijac.15152","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814966","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}

The phase composition, microstructure, and thermal shock resistance of the composite powders and coatings were analyzed to explore the influence of CeO2–La2O3 codoping and powder preparation techniques on the microstructure and performance of the coatings. The results indicate that the addition of CeO2 and La2O3 enhances the phase stability of YSZ coatings, reduces thermal conductivity, and significantly improves thermal shock resistance. The preparation method of the spray powder affects the morphology of the powder and the solubility of rare earth elements in the YSZ coating. Compared to the mechanical mixing method, the spray granulated CeO2–La2O3–YSZ composite powder exhibits good agglomeration and spherical morphology. After plasma spraying, the rare earth elements are more thoroughly dissolved in the coating, resulting in a uniform microstructure, higher bonding strength, lower thermal conductivity, and better thermal shock resistance.
