Li2Co(WO4)2 ceramics are promising candidates owing to their relatively low sintering temperature and favorable dielectric properties. In this study, high-purity Li2Co(WO4)2 ceramics were synthesized via a conventional solid-state reaction route using Li2CO3, CoO, and WO3 as raw materials. The thermal behavior of the precursor powders was evaluated by thermogravimetry–differential scanning calorimetry and derivative thermogravimetry, while phase formation, microstructure, densification, and microwave dielectric properties were investigated for ceramics sintered at 625°C–700°C. Thermal analysis indicated that calcination at 600°C largely suppressed the major mass-loss processes, while X-ray diffraction confirmed the formation of phase-pure Li2Co(WO4)2 ceramics after sintering. The sample sintered at 675°C achieved the highest bulk density of 6.467 g·cm−3, corresponding to a relative density of approximately 93.55% and an estimated total porosity of approximately 6.45%. Correspondingly, the best overall microwave dielectric properties were obtained at 675°C: εr = 12.488, Q × f = 10,979.1 GHz, and τf = −71.95 ppm/°C. Comparison with literature-reported values suggests that Q × f is particularly sensitive to processing conditions and microstructural defects. These findings provide guidance for controlling densification and dielectric loss in tungstate-based ULTCC ceramics.\u0000 </div>","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"23 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149145917","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 examines how prior oxidation history, defined by cyclic exposure temperature and duration, affects the thermal shock response of monolithic ZrC. Near-stoichiometric specimens were oxidized in atmospheric air across a temperature range of 600°C–800°C, then water-quenched from those temperatures. Increasing oxidation severity produced thicker oxide scales, higher monoclinic ZrO2 content, and greater crack density. A transition to failure-prone behavior occurred between 700°C and 800°C, when monoclinic ZrO2 and crack density both exceeded approximately 10%, leading to critical degradation. Given the oxidation parameters explored, the temperature threshold for thermal shock occurrence was identified as 700°C–800°C. The combined oxidation–quench approach establishes oxidation-dependent thresholds for thermal shock resistance and provides a framework for evaluating the stability of oxidized structures in harsh thermal environments.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"23 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ijac.70284","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149048083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review focuses on two advanced strategies—elemental doping and multilayer architectures—to overcome these limitations. Metal doping (Ag, Cu) and nonmetal doping (Si, F) adjust the sp3/sp2 ratio, reducing internal stress while improving toughness and adhesion. Silicon enhances hydrophilicity and tribochemical stability; fluorine increases hydrophobicity, reducing protein adsorption and platelet activation; silver or copper imparts antimicrobial properties. Multilayer designs like nanolaminates relieve interfacial stress and boost load-bearing capacity, significantly improving wear resistance and adhesion on polymers. Despite the remarkable progress, the path to clinical maturity requires overcoming persistent challenges. Achieving precise control over dopant distribution and release kinetics is paramount to ensuring long-term therapeutic efficacy without toxicity. Furthermore, ensuring robust interfacial adhesion in complex multilayer architectures under physiological duress remains a critical engineering challenge. A deeper biological understanding is also needed to decipher how coating microstructure and wear debris characteristics orchestrate the immune response and long-term tissue integration. Overall, doped and multilayer DLC coatings hold great potential to enhance the durability of next-generation biomedical devices.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"23 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ijac.70282","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149048028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
