Abstract

The invention relates to a one-part, fire resistant ceramic composite structure consisting of at least two adjacent layers. The substantial mass portion of the layers consists of an identical, fire-resistant ceramic material, and the remaining mass portion is selected in relation to each layer in such a manner that at least one layer couples inductively subject to the influence of a magnetic field, whereas at least one other layer does not couple subject to the influence of said electromagnetic field. However, all layers have the same thermal coefficient of expansion.
