Abstract: Mullite whiskers have the properties of high temperature resistance,good wear resistance,good oxidation resistance,low thermal expansion coefficient,and good thermal shock resistance,which are an excellent reinforcing agent for composite materials.Preparation methods of mullite whiskers,including solid-state methods,molten salt methods,and sol-gel methods,were introduced.Meanwhile,the vapor-solid (VS) and liquid-solid (LS) growth mechanisms of mullite whiskers were analyzed.The applications of mullite whiskers in ceramic toughening,thermal insulation,separation and filtration,and polymer performance optimization were summarized.Combined with the current problems of the preparation and application of mullite whiskers,the future development of mullite whiskers was prospected.

Key words: mullite whiskers, growth mechanism, porous ceramics, strengthen, toughen
