Abstract

Es wird ein keramisches Festelektrolytmaterial insbesondere für Sensorelemente zur Bestimmung der Konzentration von Gaskomponenten in Gasgemischen beschrieben, dessen Grundgerüst im wesentlichen aus Oxiden, Nitriden und/oder Carbiden eines ersten Elements besteht. Das Festelektrolytmaterial enthält im wesentlichen kein weiteres Element, das die elektrische Leitfähigkeit des Festelektrolytmaterials erhöht.
