Ceramic Hermetic Seal

The ceramic experts for advanced ceramics ballistics protection and total hermetic solutions ceramtec north america is a world leader in ultra high vacuum seal technologies as well as a leading supplier of various advanced ceramic products.

Ceramic hermetic seal.

Complete hermetics is a custom manufacturer of glass to metal ceramic to metal hermetic seals and feedthroughs. The elan 46 ceramic glass composite has unique properties that allow for the ability to vary the coefficient of thermal expansion and can therefore form hermetic seals with a variety of metals. Choose a metal such as kovar with the most closely matched expansion to the ceramic when possible. The metal selected to be bonded to the outside diameter of a ceramic should have a thermal expansion al2o3.

Our team has a wide range of knowledge to design and develop the hermetic connectors hermetic packages hermetic headers vacuum viewports hermetic seals and hermetic feedthroughs to fit your specifications. Maximum solid metal pin diameter is 060 where pin is brazed directly to ceramic id. Hermetic vacuum sealed ceramaseal products are built to endure extreme conditions. Hermetic seal products include qualified military connectors high pressure high temperature hpht bulkhead connectors very high temperature connectors and ruggedized connectors that combine glass seals with advanced peek polyetheretherketone molding technology.

That means that any material in the container whether it s a gas liquid or solid will not leak from the container. Our ceramic to metal seals incorporate the patented kryoflex polycrystalline ceramic and are an alternative to conventional compression glass and metallized alumina ceramics. Hermetic epoxy seals also offer the design flexibility of sealing either copper alloy wires or pins instead of the. Epoxy hermetic seal designs can be used in hermetic seal applications for low or high vacuum or pressures effectively sealing gases or fluids including helium gas to very low helium gas leak rates similar to glass or ceramic.

Place ceramic in compression rather than tension. Ceramaseal hermetically sealed to endure cold heat or high pressure. Since ceramax seals are more compatible than glass with high expansion metal alloys including aluminum titanium and stainless steel the customer was able to enjoy the benefits of stainless but have a hermetic seal that can better withstand temperature extremes. Winchester s ceramic hermetic sealing provides.

Ceramtec north america pioneered the science of ceramaseal ceramic to metal sealing more than 60 years ago and is still the world leader in ceramic to metal sealing technology today. Hermetic sealing is commonly used to encase electrical mechanisms as well as to contain functional gases.
