Abstract

Low-temperature brazing of ceramics in air enviroment by using 50Bi 2 O 3 –45B 2 O 3 –5SiO 2 glass was studied. Bi–B–O system crystals were found in the BBS glass under a parameter of 580 °C/5 min at wetting experiment, which was identified as Bi 4 B 2 O 9 . No obvious crystallization were found in all the joints brazed at 575-675 °C, shear strength of joint brazed at 650 °C/5 min reached the maximum value of 53.9 MPa. At this temperature, fracture of the joint was mainly deep striations and microcrack. Fracture of joints was smoother with the decrease of mechanical properties.
