    摘要： The invention relates to composite systems having at least two layers which comprise different inorganic, ceramic phases and are produced by cosintering of different, finely divided inorganic materials arranged in layers. The composite systems are characterized in that at least two adjacent layers comprise a dense phase largely free of macropores. The layers are durably bonded to one another by sintering together of particles of the different materials at the phase boundary or boundaries. The composite systems and the processes for the production thereof are used, for example, in the manufacture of gas sensors.

    摘要： A ceramic layer system including at least two layers having respective ion conductivities which are substantially different includes a substrate layer composed of a ceramic material and having substantially no ion conductivity; and at least one conducting layer positioned adjacent to the substrate layer, containing coated ceramic particles composed of ceramic particles composed of a ceramic material having no substantial ion conductivity which are coated with a material having a substantial ion conductivity so that each conducting layer of the at least one conducting layer has a continuous phase after sintering composed of the material which has a substantial ion conductivity and so that the at least one conducting layer has an ion conductivity effective to conduct ions. A method of producing a gas sensor for detecting small quantities of at least one gas in gas mixtures includes providing a substrate layer composed of ceramic particles composed of a material having substantially no ion conductivity; applying a layer composed of coated ceramic particles onto the substrate layer, the coated ceramic particles being composed of ceramic particles composed of a material that has no substantial ion conductivity coated with a material which has a substantial ion conductivity at the operating temperature of the gas sensor; applying at least one functional layer onto the layer composed of coated ceramic particles to provide a green body; preheating the green body to remove binding agents, plastifying agents, and any additional organic constituents; and sintering the green body after preheating by heating to a temperature effective to sinter the green body so that the layer comprised of coated ceramic particles has a continuous phase comprised of the material which has a substantial ion conductivity.

    摘要： The invention relates to a measuring sensor having pump reference for measuring the oxygen content of gas mixtures, particularly exhaust gases of internal combustion engines. The sensor includes a measuring cell (A) and a reference cell (B) each having a pair of electrodes, with one of each respective pairs of electrodes being common to the two cells, and having a fixed electrolyte. Reference cell (B) has defined therein an internal oxygen reference zone which is hermetically sealed from the gas mixture and which is connected to the atmosphere by way of a pressure-equalization line. The measuring cell (A) and the reference cell (B) can be heated by heating apparatus to a temperature at which the fixed electrolyte has an ionic conductivity which is sufficiently high. The heating apparatus and a porous insulation are advantageously disposed in the vicinity of the electrode of the reference cell which is not in common with the measuring cell and which is porous so that the porous insulation, together with the porous electrode, form the internal oxygen reference zone and, together with the porous electrode and its porous conductor track, form the pressure-equalization line.

    摘要： A measuring sensor for determining oxygen content in a gas mixture including exhaust gases of internal combustion engines, includes a base substrate which is comprised of a base material and which is electrically insulating; and an electrochemical measuring probe and an electrochemical reference probe arranged separate from each other on the base substrate. The measuring probe includes at least one internal electrode; at least one solid electrolyte island; and at least one external electrode. The measuring probe additionally includes a diffusion barrier. Further base material layers composed of the base material are provided so as to embed at least the diffusion barrier, the at least one internal electrodes for the measuring probe and the internal electrode for the reference probe. A diffusion hole is defined between the measuring probe and the reference probe which extends from the base substrate through the diffusion barrier and respective base material layers, and out to the gas mixture to be measured. Thermal stress and the accompanying tendency to cracking is reduced by providing the solid electrolyte as islands. Separate disposition of the measuring probe and the reference probe, i.e., without a common electrode, permits construction as individual layers using, for example, screen printing.
