冷冻铸造，即通过溶剂固化形成多孔结构的模板，在过去几年中得到了大量的努力。特别令人感兴趣的是多孔冷冻铸造陶瓷所表现出的独特结构和性能，这为多孔陶瓷领域开辟了新的机遇。本次审查的目的是提供对当今工艺的初步了解，特别关注结构形成机制的基本原理以及工艺参数对结构的影响。该分析强调了当前对过程的理解和控制的局限性。针对当前的成就、利益和已确定的问题给出了一些观点。
Freeze-casting, the templating of porous structures bit the solidification of a solvent, have seen a great deal of efforts during the last few years. Of particular interest are the unique structure and properties exhibited by porous freeze-casted ceramics, which opened new opportunities in the field of cellular ceramics. The objective of this review is to provide a first understanding of the process as of today, with particular attention being paid on the underlying principles of the structure formation mechanisms and the influence of processing parameters on the structure. 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.
