Freeze-casting of porous ceramics have seen a great deal of efforts during the last few years. The objective of this review is to provide a first understanding of the process as of today. This analysis highlights the current limits of both the understanding and the control of the process. A few perspectives are given, with regards of the current achievements, interests and identified issues. 2 Abstract Freeze-casting, the templating of porous structure by the solidification of a solvent, have… Expand
