  • About author:Wang Tao, born in 1995, gained his bachelor’s degree from Xi’an Jiaotong University in 2018, majored in inorganic non-metallic materials. Currently, he is studying for his master’s degree in inorganic non-metallic at the State Key Laboratory for Mechanical Behavior of Materials in Xi’an Jiaotong University. His main research direction is the preparation of porous alumina ceramics.

Abstract:

Porous alumina ceramics are widely used in various fields because of their unique characteristics in structure and properties. This article mainly provided an overview of preparation techniques of porous alumina ceramics; besides, the principles and the characteristics of pore-forming agents processes, gel-casting processes, freeze-casting processes, anodizing processes and other common processes in obtaining the required properties of porous alumina ceramics were introduced. Meanwhile, the relevant applications and the performance of porous alumina ceramics were described. The research prospects of porous alumina ceramics were put forward based on the research status at the end of this paper.

Key words: alumina, porous ceramics, preparation, application
