The microstructure, mechanical properties, thermal insulation, and ablation behaviors were investigated. Cr2AlC ceramics notably enhanced the compressive strength of CBCQF in the XY direction and reduced the room-temperature thermal conductivity in the Z direction. Most importantly, Cr2AlC ceramics significantly improved the ablation resistance of CBCQF. When 40% Cr2AlC ceramics were added, the linear and mass ablation rates of CBCQF were reduced by 38.0% and 93.2%, respectively, compared to the reference sample. Moreover, the study of ablation mechanisms revealed that the improvement in ablation resistance was primarily derived from the formation of the surface protective oxides as well as the reinforcement of oxidation resistance. Overall, this study presents a promising avenue for the application of Cr2AlC ceramics and the modification of fiber composites.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180363","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 research methodology involves synthesizing HAP and 3% silver-doped hydroxyapatite (Ag-HAP) via the sol–gel method, followed by comprehensive characterization using X-ray diffraction, Fourier transform infrared, Raman spectroscopy, and field emission scanning electron microscopy, antioxidant, thrombogenicity, and cell viability. The investigation reveals that Ag-HAP exhibits superior antioxidant properties and thrombogenicity compared to other metals doped so far. Remarkably, Ag-HAP demonstrates moderate clotting behavior compared to HAP. Additionally, the (3-(4, 5-dimethythiazol-2-yl)-2,5-diphenyl tetrazolium bromide) MTT assay evaluates cellular viability, shedding light on the biocompatibility of the materials. The study uncovers the potential of silver doping to enhance the antioxidant capabilities of HAP significantly, offering promising prospects for orthopaedic implants. The antioxidant activity of the materials is evaluated through a 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay, whereas the thrombogenicity is assessed using a whole blood clotting method. The improvement indicates that incorporating silver ions influences HAP crystalline structure and increased grain size, contributing to enhanced antioxidant efficacy and favorable cellular responses, thus underlining the potential of Ag-HAP for advanced implant materials in orthopaedic surgery. The results also discuss that how Ag-HAP is better than Co-HAP.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180366","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 frequent failure of saggar causes a lot of waste, which could be reduced by choosing corrosion-resistant materials. To understand the corrosion mechanism in the system MgO–Al2O3–SiO2, the materials MgO, Al2O3, MgAl2O4, and SiC (instead of SiO2) were embedded in premixed NMC precursor and calcined at T = 780°C for 50, 100, 150 and 200 h. The formed phases were determined by phase and microstructure analysis. Finally, the formation of LiAlO2 and Li5AlO4 is associated with a lower growth rate of the corrosion layer compared with Li4SiO4, while MgO is inert.

Additionally, the effects of MgCl2 on the hydration behavior of HMC and the working performance of its bonded castables were also investigated. The results show that the hydration mechanism of HMC is dissolution–precipitation, and its hydration product is magnesium citrate tetrahydrate [Mg(H2O)6] [MgC6H5O7(H2O)n]2∙(8-2n)H2O. The hydration process of HMC is controlled by the concentration of the C6H6O72− ions. MgCl2 could inhibit the ionization of HMC, thereby delaying the hydration progress of HMC. The second exothermic peak was delayed from 1 to 4.8 h with increased MgCl2 content to 1.0 wt.%. The working performance of HMC-bonded castables could be improved by adding MgCl2.

One of the challenges of DLP is to develop photosensitive ceramic slurries with high solid content and low viscosity, especially for non-oxide ceramics such as silicon nitride due to the dispersion and light absorption problem. This study mainly explores the dispersibility of silicon nitride in ultraviolet (UV)-cured resins and the photocured properties of the slurry. Rheological measurements were utilized to characterize and screen different dispersants in the resin. It was found that DISPERMP is an effective dispersant. In order to improve the curing depth of Si3N4 photosensitive paste, the surface of silicon nitride powder was treated by oxidation, and organic compounds with different refractive indices were also introduced to increase the light penetration depth. It was found that glycerol with a refractive index of 1.474 resulted in the greatest improvement in the curing depth of Si3N4 photosensitive paste.

To be specific, 21 kinds of HEC-xTM (x = 0–25 mol%) samples are fabricated by a high-throughput ultrafast high-temperature sintering technique, followed by oxidation testing at 1673 K for 30 min. Among all the HEC samples, the as-fabricated HEC-0Zr samples are proved to possess the best oxidation resistance with an oxidation depth of only 53 µm. Further study on isothermal oxidation kinetics demonstrates that the as-fabricated HEC-0Zr samples follow a linear oxidation law. The good oxidation resistance of the as-fabricated HEC-0Zr samples is believed to result from the (Ta, Me)2O5 phase with a low melting point, which can promote the densification of the oxide layer.

The dependence of composition, structure, and mechanical properties on fine particle size and sintering temperature was explored. The research has determined that the most effective particle size for the synthesis of refractory materials using waste electric porcelain is 120 mesh, and the optimal temperature is 1600°C. When the temperature exceeds 1500°C, the expansion generated by the decomposition of sillimanite will counteract the shrinkage of the liquid phase reaction, thereby maintaining the morphology of the sample. This process forms a unique interwoven mullite morphology through the decomposition of sillimanite, thereby enhancing the strength of the material. As a result, the optimal bending strength of 74 MPa and the optimal compression strength of 207 MPa were obtained.
