Abstract

Sapphire plates were directly bonded with bismuth borate glass braze, 50Bi₂O₃−50B₂O₃ (mol%), at 700 °C for 20 min in air. The microstructure of the sapphire/sapphire joint was studied and the interfacial phases were characterized in detail. The results showed that Al₄B₂O₉ was the main product within the joint domain, the typical microstructure of a joint was the sapphire substrate/glassy phase + Al₄B₂O₉/the sapphire substrate.
