Ceramic-to-metal brazing

Sealing refers to the physical or chemical connection of two or more materials. Joining technology is one of the key technologies in glass and ceramic manufacturing, which can improve the product’s sealing, thermal resistance, and stability, thereby improving its reliability and service life. The connection methods between ceramics and metals include mechanical connection, adhesive connection, brazing connection, solid-phase diffusion connection, instant liquid phase connection, melting welding, self-propagating high-temperature synthesis connection, friction welding, microwave connection, and ultrasonic connection, etc. According to the connection method, it can be divided into mechanical sealing and welding sealing. Mechanical sealing mainly realizes through fasteners, sealing rings, etc., while welding sealing realizes through melting connection. According to the material type, it can be divided into glass sealing and ceramic-to-metal sealing. Glass sealing is mainly used for connecting glass and glass, glass and metal, etc., while ceramic sealing is mainly used for connecting ceramic and ceramic, ceramic and metal, etc.
