本文用玻璃焊料研究了氮化硅陶瓷的液相连接，探讨了组份（0～10wt％α－Si3N4）、温度（1450～1650℃）和保温时间（10～120min）对结合强度的影响规律．结果表明，α－Si3N4的加入提高了液态焊料的粘度，降低了焊料的流动性，导致结合强度下降．采用组份为不含α－Si3N4的纯氧化物玻璃焊料在1600℃、保温30min可以得到较为理想的结合强度．
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
