Under the aerodynamic heat effect,sapphire windows and domes are easily damaged,causing its structure and function failure. To improve the strength of sapphire at high temperature can effectively inhibit its hightemperature fracture behaviors. In this paper,according to the research results at home and abroad,from the aspects of its high-temperature failure mechanism,the new characterization methods and the methods of strengthening sapphire,the latest achievements in the field of strengthening sapphire are reviewed. Finally,the research direction of strengthening sapphire is concluded.
