A heat-insulating layer system for a metallic structural component, especially for a structural component of a gas turbine such as an aircraft engine, includes an adhesion promoting layer (), an inner contact layer (), and an outer cover layer () , whereby the adhesion promoting layer (). is disposed on a surface () of the gas turbine structural component (). The inner contact layer () is formed of a zirconium oxide partially stabilized with yttrium or yttrium oxide, and the outer cover layer () is formed of a material that consists of at least one component with at least one phase, which stoichiometrically comprises 1 to 80 Mol-% MxO, 0.5 to 80 Mol-% MyO and AlOas a remainder with incidental impurities, wherein Mx is selected from the elements chromium and barium or mixtures thereof, and wherein My is selected from the alkaline earth metals, the transition metals and the rare earths or mixtures thereof.

Heat-insulating layer system

The invention relates to a ceramic cooktop comprising a cooking plate () made of glass ceramic or glass. The ceramic cooktop also comprises an electrical heat conductor layer () and an insulating layer () that is located between the cooking plate () and the heat conductor layer (). The insulating layer () consists of a plurality of individual layers () that each have a porosity that decreases toward the heat conductor layer ().

Ceramic cooktop

An ozonizer is disclosed, having a first electrode and a second electrode between which a discharge gap is formed, a dielectric being arranged between the first electrode and the second electrode. The dielectric comprises a support element made of glass or glass ceramic, onto which a thin dielectric film on the order of up to 100 &mgr;m is applied. The use of glass or glass ceramic as the dielectric, in conjunction with an additional thin ceramic dielectric film, allows a considerable improvement in the ozone concentration in the carrier gas, simultaneously with a good ozone yield.
