Zn2+ doping was found to have a notable effect on the structural properties of the sample, as evidenced by XRD results indicating a cubic FCC structure with a ferrite spinel structure. The average crystallite size was 20.61 nm, and the lattice parameters of the samples varied slightly depending on the amount of Zn2+ doping. It was observed that Zn2+ doping increases both the magnetic moment and temperature of the sample. Zn2+ ions possess a large magnetic moment, which interacts with the other ions in the sample, resulting in an increased overall magnetic moment and coercivity. FE-SEM microstructure revealed cauliflower morphology, multiple pores, and rough aggregates. This increased magnetic moment was reflected in a specific capacitance value of 53.518Fg−1 at a scanning rate of 30mVs−1. Impedance analysis reveals that the relaxation phenomenon is highly dependent on concentration and frequency. PVP-coated Zinc-incorporated manganese ferrites are of great importance in technology and science due to their high saturation magnetization and low core losses. These ferrites have been widely utilized in electronic applications, such as magnetic storage devices, sensors, and microwave devices.","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"20 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141575246","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}

This study specifically focused on the influence of glaze particle size distribution on the thermal behavior, microstructure, and surface appearance of barium frit based ceramic glaze in the floor tile firing process. The investigation involved examining the impact of four distinct particle size dimensions (d50: 5.7 μm, 6.8 μm, 7.5 μm, 10.9 μm) on the glaze properties by using hot stage microscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), color and gloss measurements. The studies indicated that celsian is the dominant phase in the glaze structure. The sintering and softening temperatures of glazes decreased with the increase of milling time. A decrease in the particle size of the glaze slurry increased the whiteness index. As the average particle size (d50) of the glaze decreased, the number of crystals was also increased. The investigation results also suggested a relation between specular reflection and milling time. As the milling time extended, there was a corresponding increase in the magnitude of glossiness.","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"26 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141575250","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 extend the service life of the crystallizer, a high hardness WC-Cr3C2-Ni thickness gradient wear-resistant coating was prepared on the inner wall of the crystallizer via the HVAF (High-Velocity Air Fuel) spraying technology. In cyclic thermal shock environments, the thermal shock resistance of planar coatings decreased with the thickness. The coating with a thickness of 100 μm exhibited the best thermal shock resistance, with up to 25 cycles at 800 °C thermal shock. In high-temperature wear experiments simulating actual service environments, the 300 μm coating, which owned the worst theoretical thermal shock resistance, was well bonded to the substrate and exhibited good serviceability. Comprehensive experimental results showed that the WC-Cr3C2-Ni coatings deposited by HVAF were stable in practical long-cycle production. The coating preparation process proposed in this paper has been applied in domestic steel mills, effectively extending the working cycle of the production line and improving economic efficiency. This study will provide a theoretical basis for the selection and preparation of surface coatings for continuous casting crystallizers and other structures in complex service environments.","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"14 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141575251","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}

A well-known optimization technique i.e., Taguchi’s design of experiments was employed to identify the ideal dopant concentrations in HA. This approach aimed to achieve a desired dielectric constant (DC), a key electrical property, while simultaneously promoting favourable biological properties for potential tissue engineering applications. Compared to undoped HA, specific CD-HA L6 (2.5Sr-5.0Zn-2.5 F) and L9 (5.0Sr-5.0Zn-2.5Ag) compositions exhibited significantly increased dielectric constants, reaching up to 145% higher values. The finding suggest that these nutrient doped HA could be beneficial in applications where electrical stimulation play a crucial role for bone growth. Further, L6 and L9 samples demonstrated nearly double the cell proliferation rate compared to undoped HA. In addition to cell material interaction, the antibacterial activity of both undoped HA and CD-HA samples against Escherichia coli and Staphylococcus aureus bacteria was conducted successfully. Notably, the L9 (5.0Sr-5.0Zn-2.5Ag) composition displayed the strongest antibacterial effect, with the largest inhibition zone against E. coli. These aforementioned findings suggested that these bio-ceramic CD-HA compositions containing 5% Sr and Zn, along with 2.5% Ag and F can be used as the potential candidates for various biomedical applications.","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"31 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141552540","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 study, a novel mullite raw material with excellent alkali resistance was prepared by introducing kyanite tailings into low-grade raw bauxite. The effects of the microstructure, glass phase composition and phase distribution on the alkali attack resistance of such raw material were investigated. As the amount of kyanite tailings introduced increased, the glass-phase content of the specimens had little change, while the silica content in the glass phase increased obviously. Additionally, with increasing kyanite tailings content, the mullite phase gradually transformed from fine needle-like structures into columnar or tabular structures, allowing mullite to be better enclosed within the glass phase. The alkali attack test indicated that adding kyanite tailings significantly improved the alkali attack resistance of the specimens. This was explained as follows. (i) The silica-rich glass would be transformed into liquid phase during alkali attack, changing the corrosion process from the direct gas–solid reactions to dissolution–precipitation process. The formed liquid phase also densified the corrosion layer, effectively preventing further penetration of the alkali vapor. (ii) The mullite phase was wrapped in the silica-rich glass phase, preventing its direct reaction with alkali vapor and the resulting volume expansion. Besides, alkali attack resistance of the mullite phase was enhanced due to its particle coarsening.","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"6 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141547147","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 extract obtained from the pods of the bean plant was produced using the environmentally friendly green synthesis method, along with the chemical reduction method as the production procedure for the catalysts. The analyses used to study the structure and surface morphology of catalysts are SEM, TEM, EDX, XRD, FTIR, and XPS. From the SEM and TEM pictures, the shape of the catalysts comprises of tiny spheres and has a porous nanostructure, and the particle size is 35–40 nm. The XRD investigation revealed that the catalysts had an amorphous structure. The catalysts’ structure has been confirmed to include the components Co, Cr, and B using EDX and XPS analyses. It was examined how different amounts of catalyst, different NaBH4/NaOH concentrations, and different solution temperatures affected the hydrolysis of sodium borohydride. The n-th order kinetic model was utilized to determine the activation energies of Co-Cr(0) and Co-Cr-B nanocatalysts, which were found to be 24.39 kJ/mol and 43.09 kJ/mol, respectively.

Among the five glass compositions analyzed, ATSAg0.50, containing 0.50 mol% Ag2O, stood out due to its superior density and attenuation coefficients, suggesting enhanced shielding capabilities. Our methodology encompassed detailed assessments of linear and mass attenuation coefficients, alongside parameters like the half-value layer (HVL), mean free path (MFP), and transmission factors (TFs), across a wide photon energy spectrum. Notably, ATSAg0.50 exhibited the lowest TFs and shortest MFP, indicating its potential as an efficient shield against gamma radiation. Furthermore, its high linear attenuation coefficients across all energies emphasize the pivotal role of material composition and density in effective radiation protection.
