Ceramics Bonding Using Solder Glass Frit
نویسندگان
چکیده
Ceramics bonding is becoming an important technology and has found wide applications in different engineering and electronic industries. In this paper, furnace bonding of ceramics using solder glass frit was investigated with emphasis on the effects of surface treatment and bonding conditions on bonding strength. Alumina (Al2O3) sheet and SCHOTT solder glass G017-393 were used as the base and brazing filler materials, respectively. Chemical surface treatments using various acids were tested. The results reveal the effects of spreading and voids on bonding strength. An optimum bonding strength can be produced by an appropriate combination of bonded glass-frit density and spreading area. Bonding strength is not only related to surface-contact angle but also surface roughness. The study shows that high-quality ceramics bonding or sealing can be achieved with the application of appropriate bonding conditions.

متن کاملMicrostructure and Properties of Porous Si3N4/Dense Si3N4 Joints Bonded Using RE–Si–Al–O–N (RE = Y or Yb) Glasses
The joining of porous Si3N4 to dense Si3N4 ceramics has been successfully performed using mixed RE2O3 (RE = Y or Yb), Al2O3, SiO2, and α-Si3N4 powders. The results suggested that the α-Si3N4 powders partly transformed into β-SiAlON and partly dissolved into oxide glass to form oxynitride glass. Thus, composites of glass/β-SiAlON-ceramic formed in the seam of joints. Due to the capillary action ...
