In this work, the preferential orientation of the platelets does not come from a pre-alignment step (using ice templating or magnetically assisted slip casting), but is done in a single step in parallel with the sintering of the powder . In order to maintain a fine microstructure, we used field assisted sintering (FAST) (HPD25, FCT SystemeGmbH, Germany), which allows us to combine rapid heating with uniaxial pressure of the platelets. This uniaxial pressure applied to the powder aligns the platelets: the longest dimension of the platelets (in their basal plane) is thus aligned perpendicularly to the compression axis of the powder.
