This work developed an innovative erythritol–water medium, supplemented with trace mixed organic acids, which expedited the conversion of industrial by-product gypsum into high-quality α-HH within just 1 h, outpacing the majority of documented alcohol–water systems. The resultant α-HH exhibited a large-size and short columnar form with an aspect ratio of 2.32, marking a significant advancement for the industrial-scale production of α-HH. Importantly, α-HH synthesized using erythritol showcased higher crystallinity compared to commonly employed medium such as glycerol and ethylene glycol, due to the fact that the hydroxyl groups of erythritol adhered to facets of α-HH, occupying the vacancies at Ca sites and thereby inhibiting the active growth sites. Further investigations revealed that erythritol fostered favorable thermodynamic conditions for the dissolution of dihydrate gypsum, and established a homogeneous supersaturated surrounding for the nucleation and growth of α-HH, thereby resulting in the formation of α-HH with reduced aspect ratio and improved dispersibility. This study provides a cost-effective alternative to the common glycerol–water system and chloride salt solution for waste gypsum conversion to α-HH.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770358","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 effects of sintering temperature and Y₂O₃ content on the phase composition, microstructure, and mechanical properties of PcBN composites were systematically investigated. The results show that the phase compositions of the composites with different sintering temperatures are the same. A moderate addition of Y₂O₃ enhances the formation of Sialon within the system and promotes an increase in its aspect ratio. When the Y₂O₃ content is 2%, both long columnar Sialon and needle-like (or plate-like) TiB₂ coexist, with the aspect ratio of Sialon ranging from 4:1 to 5:1. At this composition, the interface bonding is optimal. Under these conditions, the Polycrystalline cubic boron nitride (PcBN) composite exhibits the best overall performance, achieving flexural strength of 990.72 MPa, hardness of 28.49 GPa, fracture toughness of 7.8 MPa·m¹/2, and a maximum wear ratio of 1602.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770564","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}

Theoretically, the efficiency of solar thermal power plants increases with increasing working temperatures. Solar thermal power plants hardly exceed the operating temperature of 500°C due to various limitations, such as the degradation of their components and linings (mainly alloys). In this paper, a recently proposed cost-effective high-temperature chloride salt mixture that can operate up to 750°C was tested against refractory monolithics (castables) as containment materials. Low-cement castables (LCC,a type of monolithic refractory) were designed to meet the desired chemical, physical, and mechanical properties. The interaction between the refractory monolithics and the energy storage materials (molten chloride salt mixture) was investigated using X-ray diffraction (XRD), scanning electron microscopy-energy-dispersive X-ray spectroscopic analysis (SEM-EDS), and so on. The castables designed with mullite aggregates (M) have more impurities and thermal conductivity but lower porosity than hibonite aggregates (B). Negligible salt corrosion and minimal penetration were observed for both samples, but sample B did not show refractory contamination in salt.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770512","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}

However, their inherent brittleness complicates the grinding process, often leading to edge chipping and impacting machining performance. In this study, a novel spark plasma sintered α/β-SiAlON ceramic double-circular-arc end mill was designed, and a specialized grinding process was developed to address its unique geometrical features. The grinding process was systematically divided into five key steps: helix flute, Y-direction flank, chip space, secondary flank, and primary flank. Analysis of the grinding principle and surface characterization showed good ground surface quality due to the refined process and gentle grinding parameters, but significant microdefects were still observed. Material flaking, grain pull-out, brittle fracture, and crack propagation are key mechanisms in the material removal process. Machining tests demonstrated a reliable cutting performance of the developed end mill when machining Inconel 718, although tool failure ultimately occurred due to flank notch wear and rake face chipping. This study enhances the understanding of the fabrication and performance of SiAlON ceramic end mills and offers valuable insights for future developments in the field.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770302","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 physical properties, microstructure, thermal conductivity, and slag resistance of the castables were analyzed using X-ray diffractometry (XRD), scanning electron microscopy (SEM), and thermodynamic calculations. A comparative analysis was carried out between these findings and the corresponding ones for dense aggregates of Al2O3–MgO castables. Compared with dense aggregates, the reaction between microporous aggregate and matrix results in a smaller pore size in lightweight aggregate castables. The less soluble spinel in the microporous aggregate contributes to the reduced solubility of lightweight castables in slag, thus enhancing their corrosion resistance. Porous aggregates could absorb more Fe2+/Mn2+ ions from slag than dense aggregates, resulting in an increased viscosity of the slag. This, combined with the small pore size of the matrix, contributes to the superior penetration resistance of the lightweight aggregates castable compared with the dense aggregates castable. Consequently, lightweight aggregate castables exhibit superior corrosion and penetration resistance compared with dense aggregate castables. In contrast to dense aggregates castables, lightweight aggregates castables exhibit a 16.3% reduction in bulk density, an 8.2% decrease in thermal conductivity, and a notable enhancement in slag corrosion resistance.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770578","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}

At 15 N load, abrasion and oxidation are observed on worn surfaces of monolithic TaC. TaC composites with ≤ 35 vol% SiC content exhibited abrasion, pull-outs, and tribo-oxidation, while composites with ≥ 50 vol% SiC content experienced severe fracture along with tribo-oxidation.
