Field effect transistors (FETs) that include crystal indium oxide (IO) as a channel material exhibit an off-state current (Ioff) equivalent to that of the FETs that contain indium gallium zinc oxide (IGZO) and an on-state current (Ion) that is higher than that of the FETs that contain IGZO. Single crystal IO is shown to be a promising material for improving performance and reducing the variation in the characteristics of OS devices.

This study investigates the valorization of sulfidic coal mine tailings as a partial substitute for metakaolin in geopolymer synthesis. A comprehensive protocol involving mechanical grinding, particle size reduction (<5 µm), and thermal treatment at 800°C was applied to enhance the reactivity of the aluminosilicate phases and eliminate harmful sulfidic content. Unlike earlier studies that only demonstrated low substitution levels or required blending with multiple precursors, this research uniquely demonstrates that thermally valorized coal tailings can replace up to 60 wt.% of metakaolin without compromising mechanical performance—geopolymers with 50 wt.% tailing substitution achieved compressive and flexural strengths of 43.3 MPa and 8.9 MPa, respectively. These are comparable to pure metakaolin-based formulations and significantly superior to untreated tailing mixes. The findings are supported by extensive mineralogical analysis (XRD, EDS, TGA, XRF) and confirm that valorized mine tailings can serve as a cost-effective, environmentally sustainable, raw materials for geopolymer production. This approach transforms hazardous waste into valuable construction materials and supports the global transition to low-carbon building technologies.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70014","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144255808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-entropy carbides (HECs) are one such subclass of high-entropy materials where numerable interesting material compositions have been identified. However, significant barriers exist toward the scale-up of HEC fabrication beyond the pilot research and development scale. Currently, all reported fabrications of HEC materials uses processes that are not amenable to manufacturing HECs on the scale a materials supply company requires. For example, the most commonly reported synthesis routes require high energy ball milling to reduce the diffusion lengths before producing a bulk HEC article. Herein, two commercially viable routes to producing HEC feedstocks are demonstrated. The first method, cold crucible induction melting (CCIM), is a direct route to synthesize a nearly homogeneous HEC bar that can be milled into a granular powder. The second method, spray drying, produces agglomerated spherical particles that can undergo further homogenization or be used directly. The consolidation of the as-spray dried HEC feedstock into a bulk HEC article is demonstrated using spark plasma sintering (SPS). Chemistry mapping coupled with several additional analyses of the cold crucible bar, spray dried particles, and SPS densified sample are utilized to verify the products of each processing route. The future manufacturing and high-throughput screening of other high entropy ceramic materials, such as oxides, nitrides, and borides, is expected to benefit from this demonstration of rapid and commercially relevant HEC feedstock production methods.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper reports on the development and characterization of high-resistivity Pr2/3Cu3Ti4O12 (PCTO) ceramics developed by doping with Ca2+ and Sr2+ ions under various processing conditions. In particular, synthesis and growth were performed at 1173 and 1273 K resulting in significant difference in both electrical and morphological properties. To alter the distortion and polarity of ceramics, low concentration (0.15 mole fraction) of Ca2+ and Sr2+ hetero-valent ions with different size were substituted for Pr3+. The evolution and sizes of non-spherical, non-faceted grains altered to facet shapes due to changes in the anisotropy developed with increased copper concentration in the grains. The morphology analysis at these low processing temperatures revealed that grain growth occurs by engulfment of smaller grains by larger grains, necking process, and channel formation, with particles growing in nanometer size to greater than 10 µm and forming new layers on top of grains. The migration of copper-rich phases above 1173 K from boundaries to grains causes faceted morphology in both pure and substituted PCTO. Finally, by substituting Ca2+ and Sr2+ into the ceramics, altering the processing temperature, resistivity, and dielectric constant significantly increased. The substituted ceramics showed a higher dielectric constant at applied frequencies of 100‒100 000 Hz and did not vary at bias voltages of 50‒1000 mV, indicating no breakdown of the ceramics.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"7 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143919366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The microstructure of varistor was characterized by Voronoi network, and the relationship between microstructure and electrical properties was studied by experiments. The results of the calculations indicate that the reduction of grain size leads to a linear increase in voltage gradient but also reduces the energy handling capacity and current-carrying capacity. An increase in grain nonuniformity causes a decrease in voltage gradient and leakage current, while the nonlinear coefficient and residual voltage ratio increase. The variation of grain resistivity significantly affects the residual voltage ratio, and the two are almost proportional. When the grain resistivity reaches 50 Ω·m, the residual voltage ratio is as high as 2.37. The influence of grain resistivity on flow capacity has an obvious inflection point and reaches the maximum value at about 1 Ω·m, about 5000 A. The increase in sample diameter size leads to a decrease in the varistor voltage gradient and nonlinear coefficient. The results can better characterize the effect of the changes of the structure of the varistor on the electrical properties.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"7 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, several attempts such as pozzolans have been used to replace cementitious materials. Currently, limestone calcined clay cement (LC3) has gained prominence as a solution to ensure sustainability in the construction industry. To this end, this work investigated the effect of gibbsite in lithomargic clay on the physical and mechanical properties of LC3. The gibbsite and kaolinite fractions in lithomargic clay were separated using the 90 µm mesh. Geotechnical analysis was performed on <90 µm clay to ascertain its suitability as supplementary cementitious material and further calcined at 800°C for 1 h. Paste cubes were produced from LC3 and cured at 7, 14, and 28 days. The compressive strength results for all gibbsite-containing formulations after 28 days were above 20 MPa; thus, can be classified as type M masonry cement. Furthermore, the density of LC3 cubes, which has a relationship with compressive strength was seen to increase as curing age increased, thus corresponding to an increase in compressive strength, which has the potential to enhance the resistance of LC3 paste cube specimens to harsh environmental conditions.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"7 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
