Brazing experiments were performed at 830°C for Al2O3/Al2O3 and Al2 O3/Fe-Ni-Co alloy joints, which are used in electronic and structural applications. The brazing was done with Ag-Cu and Ag-Cu-Ti and changes in fracture mode and fracture strength of the Al 2O3-Al2O3 joint were investigated after heat treatment at 400 and 600°C for 100 h. For as-brazed samples, the fracture occurred within Al2O3 , but a long heat exposure at a medium temperature caused the fracture path to move to the joint region. For the ceramic-metal joining, Al2O3/Fe-Ni-Co alloy joints were prepared with a variety of interlayers. Among the interlayer materials, a Mo-Ni double-interlayer provided the highest fracture strength. The fracture strength of the joints was measured and interpreted in terms of microstructure changes
