“…In the joining temperature range of this experiment, the Gibbs free energy of all the reactions is negative, and there is a possibility of occurrence during the joining process. According to the Zr–Si–C system, the reaction of Zr with SiC can be simply classified into two types: the first type is shown in Reaction (3), 28 where Zr reacts with SiC to generate ZrC and Si; the second type can be expressed as the reaction of Zr with SiC to produce ZrC and Si–Zr compounds. However, no other products like Si or Zr–Si compounds except ZrSi 2 were detected.…”

For the joining temperature of 1300 • C and 1400 • C, part of interlayer peels off from the substrate, which explains the relatively low intensity of ZrSi 2 compared with SiC in Figure 9.…”

ZrSi2–SiC powder was employed as the joining material to join SiC ceramics in this study. The effects of SiC particle (SiCp) content and joining temperature on the phase composition, microstructure, and shear strength of SiC joints were studied and reported for the first time. Research results showed that introduction of SiCp into the interlayer improved the mechanical performance of the joint. When 10 wt.% SiCp was introduced into the interlayer, the optimal shear strength measured of the joint was 116.7 ± 6.7 MPa under the joining condition of 1500°C for 10 min. With the joining temperature increased, the shear strength of the joint gradually increases. When the joint was performed at 1600°C for 10 min, an ultra‐high temperature phase of ZrC was detected in the interlayer, and the shear strength of the joint was 168.1 ± 12.6 MPa. The SiC joint with high mechanical strength might have the potential for application in the field of nuclear industry.
