“…12 Ceramic membranes are composed of several metal oxides, such as alumina, titania, silica, or zirconia, or a mixture of these oxides, which are costly. For example, the preparation costs of a porous tubular membrane using alumina range from USD 500 to USD 1000/m 2 , 10,13 while the preparation costs of a ceramic membrane based on natural kaolin were about USD 130/m 2 . 14,15 In addition, ceramic membranes prepared from conventional ceramic materials are considered inappropriate for separation/purification processes because they require a high sintering temperature of over 1500 • C during the membrane fabrication process to obtain the optimum balance between porosity and mechanical strength.…”

“…16,19 The porous ceramic supports often break at the seal and membrane interface due to weak bonds between the fibermatrix interface and the inherent brittleness of ceramic materials. 5,10 Therefore, ceramic membranes must possess strong mechanical properties to ensure their sustainability and effectiveness in separation/filtration processes. 6 Membrane fouling is also a significant drawback in the wide-ranging applications of ceramic membranes.…”

Ceramic membranes offer considerable promise for future industrial applications due to their superior chemical, mechanical, and thermal stabilities, resistance to harsh operating conditions, and long‐term operating processes. However, several bottlenecks still limit their commercial scale‐up in filtration and separation applications, including brittleness, the high costs of conventional ceramic materials, and fouling. Despite several articles in the literature on ceramic membranes, this review focuses on recent progress, technical strategies, and methods to mitigate these limitations that significantly impact their separation and filtration performance. The use of alternative naturally occurring ceramic materials to mitigate the high costs of conventional ceramic materials is discussed, as well as strategies to improve the mechanical strength of brittle ceramic membranes by increasing sintering temperatures and using support materials. Additionally, advanced techniques to mitigate fouling accumulation and wetting in the pores and on the ceramic membrane surface, such as increasing membrane hydrophilicity and surface modification, are addressed. Despite progress in technical solutions for mitigating the bottlenecks of ceramic membranes, these limitations persist. Therefore, the present limitations and future research directions are highlighted.
