Abstract: The liquid phase bonding of silicon nitride ceramics by using glass adhesives was studied. The effects of adhesive composition
and joining conditions such as temperature (1450~1650℃) and holding time (10~120min) on the bond strength of the joint were
investigated. The results showed that increasing viscosity of the adhesive by the addition of α-Si3N4 powder to the glass, and
consequently reducing fluidity of the adhesive degraded the bond strength. The op

Key words: silicon nitride, bonding, bond strength
