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
