In particular, glazed foam ceramics are often employed for external wall insulation systems. Although artificial accelerated aging tests are often conducted to study the durability of such kind of composites, experimental research on natural and artificial aging of foam ceramics is still at its early stage. In this work, the aging tests consisting of 80 hot-rain cycles and 8 months of natural aging were carried out on foam ceramics. Special attention was paid to their compressive strength, tensile strength, compressive modulus of elasticity, bonding tensile strength, and bonding shear strength. The results revealed that the compressive strength and tensile strength of foam ceramics were not significantly affected by aging. Moreover, the bonding shear strength between ceramics and adhesives has drastically increased, while that between adhesives and cement has dropped, indicating the damage risks of the interface. Besides, the acceleration rate of the bonding tensile aging strength of foamed ceramics was found to be 12.16, while that between adhesives and cement was 5.44. The findings of this research provide the innovative experimental data on the aging of foam ceramics, but also inspiration for further study of artificial aging acceleration rate.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"61 2","pages":"615 - 636"},"PeriodicalIF":1.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892706","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}

Relative density, hardness, and fracture toughness were measured by Archimedes’ principle, micro Vickers hardness testing, and crack length measurement, respectively.

Thermodynamic evaluation revealed the synthesis temperature decreases by approximately 100 °C in the presence of C.B_n/GO/Gr additives. The highest relative density (99.4%) was obtained in the sample containing C.B_n. The introduction of ZrO2 and C.B_n/GO/Gr additives resulted in a decrease in the hardness of B4C decreases. The highest fracture toughness (5.7 MPa m^0.5) was obtained in the sample containing GO, while the lowest was observed in the sample without C.B_n/GO/Gr additive (3.9 MPa m^0.5).

The search for novel antibiotics and their introduction into the pharmaceutical industry are very difficult tasks. Consequently, it is crucial to develop novel approaches to combat bacterial resistance and stop bacteria from becoming resistant. Although ferrites and zinc oxide are widely used in mechanical, chemical, and electrical engineering, little is known about their potential as biomaterials. The goal of this work was to synthesize a novel antibacterial composite containing ZnFe₂O₄ and ZnO doped by Ho. A vibration sample magnetometer (VSM), field emission scanning electron microscopy (FESEM), and X-ray diffraction (XRD) were used to characterize the produced antibacterial. The crystallite size of prepared sample is calculated to be 16.7 nm, as shown by X-ray diffraction (XRD). The images from the field emission scanning electron microscope (FESEM) depict the samples’ morphology. The platelets in the sample are spherically formed and have a hexagonal shape.

The optical band gap (E_g) was measured to be 2.3 eV. Intermolecular interaction raises the refractive index of the nanocomposite, while interfacial polarizations and widening band gaps at the conductor-insulator interface are responsible for its high optical conductivity.

The calcination process involved two distinct temperatures: 850 °C (Group A) and 910 °C (Group B), each sustained for a duration of 24 h. Following calcination, the samples underwent sintering at varying temperatures: 920 °C, 950 °C, and 980 °C.

The characterization techniques employed encompassed thermogravimetric analysis (TGA/DTG), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and four-point probe measurements (4PP).
