“…Thus, nonmetal interlayer needs to be developed to join ceramics to avoid the generation of the residual stress. The recent literature reported that alumina can be bonded well by ceramic interlayer such as Al 2 O 3 and SiC. Particularly, B 2 O 3 was used to join alumina by transient liquid phase forming whiskers in the joint.…”

Alumina was successfully joined to itself in air environment by B2O3 + Al2O3 powder mixture as the interlayer to synthesize aluminum borate whiskers in the joint. The microstructure evolution was analyzed by means of scanning electron microscope (SEM) and X‐ray diffraction (XRD). The possible mechanism of microstructure evolution was also discussed. The effects of parameters such as heating cycles and temperature on the microstructure as well as the 3‐point flexural strength of the joint were investigated. It was found that heating the specimen for several heating cycles instead of holding at a constant temperature for a long time can eliminate the voids among the whiskers to achieve a dense microstructure, and the phenomenon that higher temperatures can accelerate the reaction was also observed. The highest strength of the joint reaches 90.29MPa with the heating temperature of 800°C after four heating cycles.
