High Temperature Ceramic Feedthrough

3x safety factor required for pressure. Ceramic to metal feedthroughs not only offer absolute freedom from leaks in vacuum and ultra vacuum environments but are also resistant to high temperatures cryogenic temperatures high pressure and aggressive chemicals. Ceramics are extremely reliable in high vacuum applications and compatible with metals such as titanium alsi kovar alloy 42 cumo and cuw.

Ceramic feedthroughs are ceramic to metal fabrications that are utilized to transmit electrical signals high currents gases fluids or high voltages from between external sources to and a hermetically sealed chamber.

High temperature ceramic feedthrough.

In order to meet requirements of these markets sct offers solutions of ceramic feedthrus with very high operating performance resisting to radiation high pressure high electric voltage corrosion and high temperature. Adtech ceramics is the us leader in manufacturing ceramic feedthroughs for use in military aerospace medical and high reliability industrial applications. This makes them ideal for use under such conditions. These assemblies are made to provide high mechanical strength and electrical insulation.

Adtech has a patented split via concept to provide an exceptionally reliable method of edge metallization without concern for processing damage at the point where metallization wraps around the edges. Assembly must be rated to 4160 vac at 0 5 amps while operating to 500 degrees f and 500 psi. Electrical feedthrough was required for connecting 9 foot conductor cables inside a vessel. Extended ceramic isolator was required to clear 2 5 thick vessel wall and mount flange.

Thanks to its manufacturing experience and in house r d program results related to temperature resistance increase of ceramic to metal brazed assemblies in harsh environment sct is able to develop high temperature feedthrough for operating temperature up to 1300 c 2370 f. For the design of new ceramic to metal brazed assemblies the use of cad software such as ansys q3d and maxwell provides.
