In this study, a modified high temperature adhesive based on polyborosilazane preceramic was developed for joining graphite. The properties of adhesive as well as bonding performance of both directly cured joints and calcined joints were investigated. The results showed that the shear strength reached the highest value 13.6 MPa after calcination at 1100°C due to the formation of heat‐resistant ceramic phases and solidification of molten species during joining process. Besides, the compressive shear strength of cured adhesive without posttreatment was kept above 6 MPa during test from RT to 1100°C, which made it possible applied directly in practical high temperature environment.
