Joining ZrO2 to Al2O3 Ceramics Using Al2O3-ZrO2-SiC Slurries

The joining of sintered ZrO2 to Al2O3 ceramics was realized using Al2O3-ZrO2-SiC interlayer composites, which was designed according to the Al2O3-ZrO2-SiO2 ternary phase equilibrium diagram. Effects of oxidizing SiC on joining were analyzed. The microstructure and components of the joints were studied using XRD and SEM.
