Freeze-casting applied to ceramic materials: a short review of the influence of processing parameters

“…When the freeze-casting method is applied to obtain ceramic pieces from powder particles, this method consists basically of four steps: 1) preparation of the aqueous or non-aqueous ceramic suspension; 2) molding and freezing of this suspension; 3) sublimation of the solidified solvent, and 4) sintering. The last step consolidates the ceramic walls while maintaining the pore structure and preserves a replica of the solidified structure of the solvent [7,12,13,[38][39][40]. Fig.…”

A novel process to high‐strength and controlled‐shrinkage Al2O3 foams with open‐cell by Al powder hollowing technology

“…Ceramic foams with high porosity (>90%) possess many outstanding properties, such as very low weight, high specific surface area, and excellent thermal insulation 1–3 . Such high‐performance ceramic material has proven to be satisfied the demands of many areas, for instance, energy, construction, transport, biomedical, and aerospace 4–6 . Nowadays, research on these materials focuses on the controlling of pore structure because complex and hierarchically porous have a significant influence on mechanical strength, 7,8 thermal and acoustic insulation, 9,10 filtration, 11–13 and catalytic supports 14 .…”
