Abstract

See full text

A glass-metal feedthrough consists of an external conductor, a glass material and an internal conductor. The internal conductor has a coefficient of expansion αinternal, the glass material has a coefficient of expansion αglass, and the external conductor has a coefficient of expansion αexternal. The coefficient of expansion of the internal conductor αinternal is greater than the coefficient of expansion of the glass material αglass and the coefficient of expansion of the external conductor αexternal is at least 2 ppm/K, such as at least 4 ppm/K, greater than the coefficient of expansion of the glass material αglass in the temperature range of 20° C. to the glass transformation temperature.
