Abstract

Bismuth borate zinc glass is getting increasing attention for Al₂O₃ ceramics joining due to its low melting temperature. In this paper, 50Bi₂O₃-30B₂O₃-20ZnO (mol. %) glass was successfully prepared through melt quench method. Moreover, the glass exhibited excellent wettability on Al₂O₃ surface via contact reaction wetting. Therefore, Al₂O₃ ceramics were brazed at different temperatures. Crystallization performed adverse effect on Al₂O₃/Al₂O₃ joints. As the temperature increasing, ZnAl₂O₄ particles and ZnAl₂O₄ interfacial reaction layer generated in the glass seam and at Al₂O₃/glass braze interface. Consequently, a ZnAl₂O₄ reinforced Al₂O₃/glass braze/Al₂O₃ joint with a maximum value for shear strength of 72 MPa was obtained.
