“…The main contribution to the released moisture comes from kaolin and borax, which are signi cant components of the mixture. The endothermic peak at 500-520°C on the DTG curve with a sharp decline on the TG curve is likely associated with the dehydration processes of kaolinite structures and their transformation into metakaolin [35].…”

The selective layer in a ceramic membrane is crucial for separation and filtration processes, as it endows the membrane with specific properties and functions, determining its selectivity and suitability for various applications. This study aimed to investigate the impact of the type of composition used to create a selective layer on low-cost clay ceramic membranes and to determine their physicochemical properties and permeability. In this study, a ceramic membrane substrate based on kaolin was synthesized and characterized using XRD, thermal analysis, and IR spectroscopy, and its mechanical properties were also tested. Selective layers on the ceramic membrane were synthesized with various compositions using spin-coating. They were characterized using IR spectroscopy, diffuse reflectance absorption spectrum, and scanning electron microscopy (SEM). The SEM images of all samples show a dense structure typical of clay materials. These images indicate that the composition and number of layers have minimal impact on the morphology in this case. The obtained ceramic membranes are characterized by a pore size ranging from 50 – 200 μm. The permeability of the ceramic membrane support is 40 cm3/min·cm2, which decreases with the application of selective layers. Selectivity by turbidity increases from 32% to 66.4%.

The article is devoted to the synthesis of ceramic membranes based on silicon carbide and the study of their mechanical, electrical, and antibacterial properties. SiC-based ceramic membranes have a few advantages, namely high surface hydrophilicity, good water permeability and negative surface charge, which leads to better performance during their operation. The effect of carbonate type and addition of liquid glass on the physicochemical properties of ceramic membranes was investigated using diffraction analysis and scanning electron microscopy. It was found that regardless of the carbonate type, only two phases can be identified: the main phase in the original mixture is silicon carbide and an additional phase added to the mixture is corundum. The transport properties obtained (9.03–18.66 cm3/(min·cm2)), and the results of electron microscopy indicate the macroporosity of ceramic membranes based on silicon carbide (13–20 µm). Ceramic membranes of high strength (16.3–46.8 MPa) were obtained. Studies on antibacterial properties have shown that SiC-based ceramic membranes do not exhibit antibacterial properties. The additional modification of ceramic membranes with titanium oxide has given ceramic membranes based on silicon carbide antibacterial properties, as evidenced by the inhibition of the growth of gram-negative bacteria, the effectiveness of which depends on the number of selective layers based on TiO2 applied. The results of this study are useful to enrich the knowledge of the production of silicon carbide membranes and are aimed at the future research and development of selective membranes (micro- and ultrafiltration) based on them.
