Heat resistant Ni-Sn and Ni-Si base filler Metals were developed. Wettability of Ni-Sn-Ti and Ni-Si-Ti filler metals against Si3N4 were evaluated by measuring contact angle in vacuum, and also observing the microstructure of the interface between alloys and the ceramics. The contact angle of the Ni-20Si-10Ti alloy shows the lowest among Ni-20Si alloys. The addition of Ti definitely reduces the contact angle of Cu base alloy on Si 3N 4.
