“…These materials commonly present a high volume of pores (larger than 50 nm), low density, controlled permeability, high stability at high temperatures and low thermal conductivity. Based on these properties, many technological applications can be considered such as filters at different levels (liquid metal filtration, diesel particulate filters, and molecular filters), catalysis supports for chemical processes, bioceramics (macro‐porous scaffolds for cancellous bone regeneration), structural and thermal insulating ceramics (sandwich panels for aircraft, refractories, and insulating furnace lining) …”

A direct‐foaming technique to produce macro‐porous ceramics is presented considering three key aspects: (i) a processing route without toxic additives, (ii) optimizing particle packing and dispersion of ceramic suspensions to obtain denser struts, and (iii) processing reliability for large‐scale production. To achieve the latter goal, specific foaming equipment was designed. Ceramics with large dimensions (250 × 60 × 110 mm3), high porosity level (>70%), homogeneous and narrower pore‐size distribution, high Weibull modulus (8 to 11), improved mechanical strength (3 to 15 MPa) for different compositions and low thermal conductivity at 1200°C (0.3 to 0.9 W/mK) were attained.
