“…By impregnating the carbon preforms with alkoxide solutions and applying standard sol-gel chemistry, various metal oxide macroporous ceramics have been produced using this approach. SiC-based cellular ceramics of diverse compositions were fabricated by Greil and colleagues 52,[55][56][57] via the infiltration and reaction of liquid or gaseous silicon metal with the carbon preform. Other gaseous metals and metal precursors, [58][59][60] preceramic polymers, 63 ceramic suspensions, 62 and salt solutions 64,65 have recently been employed to infiltrate the carbon cellular structure and obtain oxide, carbide, phosphate, and zeolite-containing macroporous ceramics through the wood-derived replica technique.…”

Macroporous ceramics with pore sizes from 400 nm to 4 mm and porosity within the range 20%-97% have been produced for a number of well-established and emerging applications, such as molten metal filtration, catalysis, refractory insulation, and hot gas filtration. These applications take advantage of the unique properties achieved through the incorporation of macropores into solid ceramics. In this article, we review the main processing routes that can be used for the fabrication of macroporous ceramics with tailored microstructure and chemical composition. Emphasis is given to versatile and simple approaches that allow one to control the microstructural features that ultimately determine the properties of the macroporous material. Replica, sacrificial template, and direct foaming techniques are described and compared in terms of microstructures and mechanical properties that can be achieved. Finally, directions to future investigations on the processing of macroporous ceramics are proposed.

“…For example, the high permeability and enhanced surface area of the hierarchical porous systems shown in Fig. 2.3a-c have been considered for catalytic and gas adsorption applications that require high density of reactive sites combined with fast mass transport (Zampieri et al 2005;Vakifahmetoglu et al 2010). In this case, enhanced fluid transport can be achieved with large macropores, while the high density of reactive sites arises from the pores at smaller length scales.…”

Hybrid and Hierarchical Composite Materials

The structural design of composite materials at multiple length scales is a widespread strategy found in biological materials to optimize opposing properties or to combine multiple functional properties in a unique material system. The combination of this hierarchical structuring approach with the vast chemical repertoire available in synthetic systems is expected to lead to man-made composites with unprecedented functionalities. Alternatively, hierarchical materials can potentially achieve sufficient strength and toughness even if made out of weaker environmentally-friendly or bioresorbable building blocks. Replicating the hierarchical design principle of biological systems in synthetic materials is an exciting challenge that has been tackled by researchers across different scientific communities. In this chapter, we present state-of-the-art examples on attempts to identify fundamental design principles of hierarchical natural materials and to then mimic these bioinspired concepts in man-made materials. Three selected structural features that can be independently designed at multiple length scales in biological materials are described as examples: (i) mechanical reinforcement, (ii) porosity, and (iii) topography. By comparing biological and man-made materials exhibiting these hierarchical features, we provide an overview on the limitations of currently exploited top-down and bottom-up manufacturing technologies and on the opportunities for the future development of hierarchical composites inspired by the unique multiscale structure of biological materials.

“…For instance, it has been found that the high surface area and elongated nature of the porosity makes bioSiCp an interesting catalyst carrier, especially for high temperature reactions such as partial oxidation of methane to syngas [106], cellulose conversion to hydrogen [107] using Ni particles, or catalytic combustion of hydrogen [108] but also combined with zeolites to form structured monoliths for sorption and catalysis [109,110].…”

In one approach, one selects the main microstructural features responsible for improved properties a designs processes to obtain materials with such microstructures (continuous-fiber-reinforced ceramics, porous ceramics, fibrous ceramic monoliths, etc.). In a different approach, it is possible to use natural materials directly as microstructural templates. Biomorphic ceramics are produced from natural and renewable resources (wood or wood-derived products). A wide variety of SiC based ceramics can be fabricated by infiltration of silicon or silicon alloys into cellulose-derived carbonaceous templates, providing a low-cost route to advanced ceramic materials with near-net shape potential and amenable to rapid prototyping. These materials have tailorable microstructure and properties, and behave like ceramic materials manufactured by advanced ceramic processing approaches. This review aims to be a comprehensive description of the development of bioSiC ceramics:from wood templates and their microstructure to potential applications of bioSiC materials.
