Abstract: A laminated assembly having a first layer, a second layer, and at least one sintered insulating film for electrical insulation of the first layer from the second layer. The first layer is one of a first solid electrolyte layer that conducts oxygen ions and a first electrically conducting layer. The second layer is one of a second solid electrolyte layer that conducts oxygen ions and a second electrically conducting layer. The insulating film is formed on a substrate using a paste or a suspension produced from at least one of a ceramic powder and a glass powder. One of the first layer and the second layer serves at least partly as the substrate. The sintered insulting film has a thickness ≦10 &mgr;m, and the powder is a nanoscale powder with a BET specific surface >50 m2/g and a maximum particle size of 100 nm.

Abstract: The invention relates to a mineral-insulated supply line for a sensor, including a sleeve and at least one internal conductor arranged in the sleeve, with one end of the at least internal conductor connected with a sensor element or its supply line and with the sleeve containing a mineral powder as insulation material. To obtain a high temperature-resistant and corrosion-resistant supply line for gas sensors, at least one internal conductor is made of a metal from the group consisting of tantalum, titanium, niobium, molybdenum, vanadium, zirconium, rhenium, and osmium, or of an alloy based on at least one of these metals.
