Sperry ceramic to metal sealing
WebComplete Hermetics provides custom designed ceramic-to-metal seals and feedthroughs for applications where high operating temperatures, high voltage and harsh environments are required as compared to glass-to-metal seals.These seals are more labor-intensive that glass-to-metal and therefore take longer to produce. Complete Hermetics can work with … WebElcon Precision uses proprietary technology to metallize ceramic. This process of applying a thin metal coating prepares the part for stronger brazing. Parts can range up to a 16 inch diameter and a 20 inch length. Coating thickness can range from 0.0005 to 0.0015 inches.

WebThe well-established process of ceramic to metal sealing requires a metallization layer applied on the ceramic and then secondarily brazing the metallized ceramic and the metal component together using a braze (or solder). This two-step process may sound indirect as some of the processes listed above do not require ceramic metallization. WebFeb 8, 2024 · Advantages: Ceramic to Metal sealing is considered the high-end technology and can have superior performance compared to glass in some applications: By using elastic filler-metals, the resistance to thermal and mechanical shocks is higher. Also, depending on filler-material, higher application temperatures can be sustained.
WebCeramic to metal brazing are commonly found in electrical feedthrus, laser devices and microwave tubes, etc. Due to their good performance for high vacuum, high voltage and high pressure applications, medical and military devices have more and more demands in recently years for their biocompatibility and high joint strength.
