Because it uses only mineral components, one of these compositions made of alumina platelets as bricks and a refractory phase as mortar , is particularly attractive. Materials obtained using this approach are referred to as nacre-like alumina. In addition to an increase of the resistance to crack propagation, nacre-like alumina materials exhibit, similarly to usual ceramics, high rigidity, high hardness and a good resistance to corrosion and temperature. These composites are obtained by densifying a green body composed of aligned platelets and mortar phase precursors. Several approaches have been proposed to achieve this alignment, including icetemplating or magnetic field assisted slip casting. A simpler approach was recently presented, is based on fieldassisted sintering (FAST) and is able to align and densify the material in a single process . FAST makes it possible to obtain nacre-like microstructures with a good alignment of the platelets and thus mechanical properties similar to that reported previously.
