    Abstract: A thermally tempered glass element is provided made of glass with two opposite faces that are under compressive stress of at least 40 MPa. The glass has a working point at which the glass has a viscosity of 104 dPa·s of at most 1350° C. The glass has a viscosity versus temperature profile and a coefficient of thermal expansion versus temperature profile of the glass are such that a variable (750° C.-T13)/(CTELiq-CTEsSol) has a value of at most 5*106 K2. The CTELiq is a coefficient of linear thermal expansion of the glass above a glass transition temperature Tg, the CTESol is a coefficient of linear thermal expansion of the glass in a temperature range from 20° C. to 300° C., and the T13 is a temperature at which the glass has a viscosity of 1013 dPa·s.

    Abstract: A unit for high-temperature for uses above 700° C. is provided. The unit includes a housing and an electrical functional element. The functional element has a non-conducting substrate, an electrically conductive element, and at least one connection wire or pad. The functional element has a first section, a second section, and a third section. The first section is within the housing and shielded from a local environment. The second section includes the at least one connection wire or pad and is accessible externally to the housing. The third section is between the first and second sections and is embedded in an electrically insulating material. The insulating material seals off the housing from the functional element. A physical and/or chemical bond at an interface between the insulating material and the functional element.
