Ice-templating allows the processing of YSZ samples with reproducible microstructure and porosity. The sintered ceramic monoliths fabricated in this study have a total porosity of 77.1 ± 1.5 % and the scaffolds that were cut off from these same monoliths exhibit a comparable total porosity of 78.2 ± 0.7 %. This slight decrease of porosity when removing the lower part of the sample can be explained by the higher density of this initial region. The velocity of the ice front in the transient regime is high, which results in the engulfment of a larger fraction of particles-and thus a lower porosity in the final material . Sedimentation may also explain this slight decrease of porosity in this region. We investigated the effect of PCL infiltration on porosity (Table ). As expected, the measured organic content increased with the number of infiltration cycles. In samples infiltrated with a 4wt.% PCL solution, the organic content increases from 4.0% to 10.1% when the number of cycles increases from 1 to 4. Conversely, the porosity decreases linearly with the number of infiltration cycles, as shown in Fig. .
