Custom-made Ceramic
and Glass Components
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:
Pressure
High-pressure, 20000 psi (138 MPa) seals for an oil industry application
Thermal
A ceramic-metal assembly used in an experimental vacuum furnace researching semiconductor materials
Electrical
Glass-to-metal seals in hermetic electronic packages
Vacuum
X-ray tubes and scanning electron microscope components
