Abstract:
An improved metal-to-ceramic seal is provided wherein the ceramic body of the seal contains an integral region of cermet material in electrical contact with the metallic member, e. g. , an electrode, of the seal. The seal is useful in high voltage vacuum devices, e. g. , vacuum switches, and increases the high-voltage holdoff capabilities of such devices. A method of fabricating such seals is also provided.
