“…89,141 Ceramic and metallic particles or fibers require more aggressive agents and are in most cases removed by acidic leaching. 108,142,143 In all of these processes, the continuous matrix phase has to be partially consolidated before removal of the sacrificial material, so that the porous structure does not collapse during the extraction step. When the continuous phase is a suspension of colloidal ceramic particles, consolidation is usually achieved with the help of setting agents and binders 146 or through the formation of a stiff attractive network of particles throughout the matrix.…”

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.

“…Structural macroporous SiC components have been produced by replicating polymer foams [11] or wood templates [12,13], or by using other sacrifi cial organic templates (e.g. PMMA [14] or nylon [15]), and inorganic materials (such as graphite and SiO 2 [14]). Other methods as direct foaming [16] have also been attempted for SiC.…”

“…They attributed the well-developed sintering neck to the promotion of mass transfer by nano-powders. [17,18] On the other hand, high densities of stacking faults, interfaces and nano-pores [19,20] in nano-scale microstructures will enhance phonon scattering and reduce thermal conductivity. In this paper, thermal stability and properties of porous nano-SiC prepared from 600°C to 1,800°C are investigated.…”
