            Hermetic Seals

            Hermetic seals are used where a high-integrity, electrically insulating joint is required. The components can be glass-to-metal seals or ceramic-to-metal seals, depending on the application. Such seals operate at high-pressure, vacuum, high voltage and at high temperature. The seals can also be used in less demanding applications where it is still necessary to maintain isolation between one environment and another.

            Examples include:


            High-pressure, 20000 psi (138 MPa) seals for an oil industry application


            A ceramic-metal assembly used in an experimental vacuum furnace researching semiconductor materials


            Glass-to-metal seals in hermetic electronic packages


            X-ray tubes and scanning electron microscope components
