Abstract (en)
[origin: WO0216919A2] The invention relates to a layered composite with an insulation layer for the electrical insulation of a first layer from a second layer. The first layer is embodied as a first oxygen ion conducting solid electrolyte layer or a first electrically conducting layer and the second layer is embodied as a second oxygen ion conducting solid electrolyte layer or a second electrically conducting layer. The insulation layer is formed on a support from a ceramic powder and/or a glass powder, by means of a paste or a suspension, whereby the first layer at least partly, or the second layer at least partly serves as support and the sintered insulation layer has a layer thickness of ≤ 10 mu m. The aim of the invention is to prepare a further layered composite with an insulation layer, in particular for an exhaust sensor. Said aim is achieved for the layered composite, whereby the powder used for the insulation layer is a nanopowder with a specific surface area as determined by BET of > 50m<2>/g and that the maximum powder particle size for the nanopowder is 100nm.
