Despite as much as marbling has a longstanding history in the paper, textile, and diverse decorative arts, application in ceramics is largely unexamined. In this research, both water-based and oil-based marbling formulations, utilizing traditional materials such as tragacanth, eremurus mucilage, gum Arabic, ox-gall, and linseed oil were developed and optimized for underglaze, overglaze, and colored-glaze techniques. The experimental process consisted of forming stable floating pigments and adapting designs on size, which were then successfully transferred onto ceramic bisque surfaces. Firing schedules and glaze formulas were methodically adjusted to achieve the preservation of marbled patterns following firing. The findings demonstrate that the enhanced marbling technique facilitates the development of complicated, decorative effects on ceramic substances, thereby addressing earlier restrictions with color control, pattern delicacy, and material compatibility. Among the tested approaches, the underglaze marbling method employing gum Arabic as a binder yielded the most favorable visual quality and overall performance. This cross-disciplinary development not only enriches the aesthetic potential of ceramic art but also offers a replicable approach to incorporating historic marbling processes into contemporary ceramic technologies. The results yield new knowledge on material properties, process optimization, and innovative potential of traditional processes in contemporary ceramic design.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"7 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ceramics.onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70027","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197298","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}

In this study, we investigated the applicability of a finite element analysis (FEA) approach that implements a continuum damage model embedded with a cohesive-zone relationship to predict crack occurrence and the subsequent increase in crack resistance (toughness) of ceramics. Specifically, by employing a compliance-based method, the R-curve behavior was systematically examined under a bending load to assess the impacts of fracture stress and toughness on diverse chevron-notched specimens. The output critical stress intensity factors were found to increase with the crack length, eventually converging nearly to the input fracture toughness. Subsequently, the stable crack growth behavior obtained from the FEA and experiment under a three-point bending test of high-purity alumina was compared. A consistent result was confirmed in the force–displacement relationships. Furthermore, the R-curve behavior of the target material could be indirectly evaluated using the present approach. The results support the effectiveness of the present approach, highlighting the quantitative assessment of not only crack initiation but also R-curve behavior under arbitrary boundary conditions.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"7 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ceramics.onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145101496","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 research involves the analysis of four cement slurry formulations: two without additives (with densities of 14.0 lb/gal and 15.8 lb/gal) and two with additives, including antifoaming agents, dispersants, fluid loss control, aiming to evaluate their physical and chemical resistance after exposure to completion fluids for 24 h, 30, 60, 90, and 180 days. The test specimens were aged at a temperature of 38°C and ambient pressure. The samples were subjected to compressive strength (CS) tests, x-ray diffraction (XRD), thermogravimetry (TG), scanning electron microscopy (SEM), and energy-dispersive x-ray spectroscopy (EDS). The results revealed significant concerns regarding well safety. The samples exposed to saline completion fluid for 180 days exhibited a decrease in CS, highlighting a critical issue. One of the hypotheses for this reduction in mechanical strength is the leaching of calcite from the cementitious matrix and the formation of hydrocalumite.

A review of recent literature investigated a variety of strengthening strategies from the optimization of raw material composition to the accuracy of control of printing parameters, like print rate, layer thickness, and sintering temperature. Post-processing methods like thermal treatment and isostatic pressing were also investigated for their impact. Evidence reveals that the application of infiltration and sintering processes has the effect of decreasing porosity and cracking by more than 20%, while in other cases, the printed ceramic density exceeds 98% of the theoretical density. Additionally, other studies have demonstrated that the application of different infiltration processes has the effect of increasing the flexural strength of ceramic components to more than 220 MPa, while in other cases, to approximately 350 MPa. Isostatic pressing has also been used to achieve more than 96% maximum theoretical density.

A Densification-Based Finite Element Method (DFEM) was developed for calculating the sintering distortion of ceramic parts without detailed knowledge of their constitutive law (such as viscosities and sintering potential). Given this advantage, this study presents the application of a DFEM for predicting and mitigating sintering distortion in a Full-Scale Heat Shield (FSHS) made of oxide–oxide ceramic matrix composites (Ox-Ox CMCs). DFEM was used to develop a digital twin that accurately identified geometric regions prone to distortion and quantified deviations between experimental measurements and finite element predictions. Suppression strategies were evaluated by applying boundary conditions, demonstrating a significant reduction in distortion in targeted regions. The findings highlight DFEM as an approximate yet computationally efficient approach, capable of eliminating the need for extensive material characterization, such as fiber orientations, ply numbers, matrix compositions, and sintering profiles. Instead, this information is inherently reflected in the measured sintering deformation, including distortion. This study establishes a foundation for further research into addressing distortion causes and optimizing sintering processes for improved manufacturability in aerospace applications.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"7 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705600","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}

Photonic curing of such composites by flash lamp annealing (FLA) is of interest as a new route to additive manufacturing of ceramics or rapidly producing ceramic coatings. ADP undergoes a condensation reaction with Al2O3 around 300°C–350°C and forms an AlPO4 compound that is thermally stable up to 1500°C due to strong P─O─Al bonds. Herein, an FLA system that can deliver tens of kilowatts per square centimeter of radiant energy is used to rapidly transform this ADP/Al2O3 mixture into this AlPO4 ceramic phase. An ADP fraction of about 55 vol% results in the lowest porosity layers having the best layer cohesion. Absorbance of the photonic energy emitted by the FLA's broadband xenon lamp (400–800 nm) is also critical to rapidly transforming these layers because optical absorbance is needed to convert the photonic energy to thermal energy. Three different optical absorbers—graphite, black iron oxide, and liquid black organic ink—are investigated as optical absorbers. Adding these absorbers is found to lower the required photonic input for ADP-to-AlPO4 conversion from ∼350 to ∼220 J/cm2, making the process even more energy efficient.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144551075","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}
