Abstract
An insulation element for the thermal insulation of an inductively heatable high-temperature treatment zone. A wall of the insulation element contains a flat material, the resistivity of which is ρF 10-5 to 10-1 Ωm and which encloses a hollow space extending through the insulation element and includes a discontinuity, in which the resistivity ρU is greater than ρF. The discontinuity extends from the external surface of the flat material into the flat material but does not interrupt the flat material over the entire cross section of the flat material.
