In this work we fabricated alumina samples by the freeze-casting technique using tert-
butanol as the solvent. The prepared materials were examined by scanning electron …

Freeze-casting is a promising technique for fabricating macroporous ceramics because it is
an environmentally friendly, cost effective, and easy scale-up method. Several freezing …

One of the major challenges for obtaining asymmetric membranes has been the preparation
of ceramic supports with tailored pore structures. The methods commonly used for …

This work investigated the behavior of TiO 2-containing α-Al 2 O 3 samples prepared by the
freeze-casting technique. Camphene and liquid nitrogen were used as the solvent and …

In recent years there is a high interest in the freeze-casting process because it is a simple,
economical, and environmentally friendly method for obtaining highly porous materials. Most …

The porous alumina ceramics with lamellar structure were fabricated successfully by freeze
casting. The viscosities of alumina slurries, pore structures, porosities and mechanical …

Freeze casting is a promising technique to fabricate porous materials with complex pore
shapes and component geometries. Of particular interest are the unique structure and …

Highly porous alumina systems were aimed to produce by low energy-consuming sol–gel
and freeze drying techniques. A 3D molecular gel structure derived by sol–gel method is …

Experiments have been performed to show that the mechanical properties of alumina
porous ceramics may be improved by introducing glycerol into the raw slurries and then …

A unique porous ceramic with complex pore structure was synthesized by the freeze-dry
process. A water-based ceramic slurry was frozen while controlling the growth direction of …
