“…Gel casting is a method of preparing porous ceramics by polymerizing organic monomers to form a colloid with three‐dimensional network structure, which can solidify the ceramic slurry in situ 36,154,155 . Porous ceramics prepared by gel casting have the advantages of high porosity, uniform distribution, and good mechanical strength 156 . Therefore, when preparing porous ceramics using sacrificial templates, it is necessary to select appropriate pore forming agents.…”

“…Mechanical processing is a method that uses turning, milling, grinding, and other mechanical processing methods to remove materials from the surface of materials to construct texture. Mechanical processing methods of textured ceramics include: abrasive jet machining, 172 grinding, 173–175 and microcutting 156,176 . Abrasive jet machining technology is a method of selectively removing materials and forming a microstructure by using high‐speed gas to drive abrasive impact masking film‐covered processing surfaces, as shown in Figure 13a 26 .…”

Ceramic materials are widely used in engineering field because of their good physical and chemical properties. The poor mechanical properties of traditional ceramics seriously limit the development of ceramic materials and have attracted extensive attention since its birth. The development of high toughness, light weight, and functional ceramic materials has long been the pursuit of materials scientists. Since ancient times, nature has been the source of all kinds of human technological ideas, engineering principles, and major inventions. The functional structure of biology provides a good research object for the bionic design and preparation of ceramic materials. Therefore, it is necessary to summarize the functional structures and mechanisms in nature and biomimetic preparation technology. The purpose of this review is to provide guidance for the functionalized biomimetic design and efficient preparation of ceramic materials. Some typical functional examples in nature are introduced in detail, and several representative biomimetic preparation methods are listed. Finally, the performance and application status of biomimetic ceramics are summarized, and the future development direction of biomimetic ceramic materials is prospected.
