Ceramics possess the properties of heat resistance, insulation, wear resistance and corrosion resistance. They are suitable for use in high-temperature, vacuum and corrosive environments and are widely applied in semiconductors, optoelectronics and various industrial equipment. However, they cannot independently perform load-bearing, conductive and sealing operations and need to be assembled with metals.   The difference in thermal expansion coefficients between the two is significant. After welding, stress cracking, interface separation and weak bonding force problems are prone to occur. To achieve a stable connection, it is necessary to select appropriate metal materials reasonably, along with compatible metalization treatment and welding processes. This article, based on actual application scenarios, sorts out material selection, welding processes and implementation suggestions to help optimize product design.     I. Thermal expansion-matching metals: The best choice ...

  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 ...

  Advanced ceramics have become an indispensable part of the engineering structure field due to their high strength, high hardness, excellent wear resistance, and corrosion resistance. However, due to brittleness, and poor processing performance, a single ceramic material is not enough to meet the requirements of the engineering field, the application often needs  to be connected with the better  toughness of the metal material, so that the two complement each other’s strengths, giving full play to the excellent performance of ceramics. ( 95%alumina ceramic and Kovar brazing   part)   The realization of a reliable connection between ceramics and metal is the key to promoting the application of ceramic materials. The biggest difficulty in the connection process between ceramics and metal lies in the large difference between the coefficients of thermal expansion of ceramics and metal, which generates large residual stresses at the sealing interface after the conne...
