Brazing of SiO2 ceramic

SiO2 ceramic has wide applications in various industries owing to their excellent properties. To make the most use of their properties and enlarge their applications, it is important to bond the SiO2 ceramic and metal. The brazing of SiO2 ceramic in recent years is reviewed in this article. The advantages and disadvantages of the active brazing method are discussed. The bonding between SiO2 ceramic and different types of metals is analyzed. Besides, to improve the wettability of the reaction interface, different improvement methods of filler metal are introduced. Finally, the development direction of bonding SiO2 ceramic in the future is proposed.
