FEED-THROUGH ELEMENT FOR HARSH ENVIRONMENTS

摘要

A feed-through element for harsh environments comprising with a support body with at least one access opening, in which at least one functional element is arranged in an electrically insulating fixing material. The electrically insulating fixing material contains a glass or a glass ceramic with a volume resistivity of greater than 1.0 x 10 10 .OMEGA. cm at the temperature of 350 °C. Said glass or a glass ceramic has a defined composition range in the system SiO2 - B2O3 - MO.
