英文摘要：

Silicon nitride based porous ceramics are subject to the global materials community because of the characteristics of silicon nitride ceramics and porous ceramics. The research status of silicon nitride based porous ceramics at home and abroad is summarized, the preparation technique of silicon nitride based porous ceramics is reviewed, and the pore structure control methods of silicon nitride based porous ceramic is analyzed. Based on the formula that different areas of application proposing different requirements to the material structure and properties, control technology of pore structure, control methods of the different phase composition and process costs reduction are trends of silicon nitride based porous ceramics in the future.
