Unit for high-temperature uses

A unit for uses above 700° C., comprising:

• a housing;
• and
• at least one electrical functional element having a non-conducting substrate, an electrically conductive element, and at least one connection wire or pad,
• wherein the at least one electrical functional element has a first section within the housing and shielded from a local environment by the housing, wherein the at least one electrical functional element has a second section that includes at least a portion of the at least one connection wire or pad that is accessible externally to the housing, wherein the at least one electrical functional element includes a third section that is between the first and second sections, the third section being embedded in an electrically insulating material of the housing, wherein the electrically insulating material seals off the housing from the at least one electrical functional element, and wherein the electrically insulating material is selected from a group consisting of a glass, a glass ceramic, and a combination or a composite of glass and glass ceramic;
• and
• a physical and/or chemical bond at an interface between the electrically insulating material and the at least one electrical functional element, wherein the first section is in a cavity of the housing, wherein the cavity is evacuated or filled with an inert gas.

• and
• a physical and/or chemical bond at an interface between the electrically insulating material and the at least one electrical functional element that provides a hermetically sealed connection between the electrically insulating material and the at least one electrical functional element by fusing the electrically insulating material onto the electrical functional element.
